This document summarizes 5 papers on researching CSRF protection in web frameworks.
Paper 1 analyzes CSRF mitigation levels in popular JavaScript frameworks and finds that Express, Koa, and Hapi provide level 3 protection through plugins, while Sails has level 4 built-in protection and Meteor level 5 through architecture.
Paper 2 surveys CSRF defenses across frameworks and maps them to threats. It finds defenses are inconsistently implemented and most frameworks combine multiple defenses.
Paper 3 presents an algorithm called Mitch that uses machine learning to detect CSRF vulnerabilities as a black-box by analyzing differences in responses to sensitive versus insensitive requests.
Paper 4 also uses machine learning for CSRF detection and tests it on existing
The document proposes a novel distributed network architecture for enterprise network vulnerability assessment using CORBA. It discusses limitations of current vulnerability assessment solutions, such as inflexibility in distributing scanning tasks across multiple scanners. The proposed architecture would dynamically assign scanning tasks based on scanner availability to improve efficiency and reliability. It would also decrease the size of individual scanning tasks to speed up task reassignment in case of issues. The architecture follows CORBA standards to define interfaces for communication between distributed components for vulnerability detection and remediation across an enterprise network.
The document describes a hardware-assisted approach called Dynamic Information Flow Tracking (DIFT) to provide practical and efficient software security. A flexible hardware design is proposed that works with unmodified binaries to track tainted data from untrusted sources and check for unsafe uses. A key idea is to offload DIFT operations to a separate coprocessor to minimize changes to the main processor core while providing robust, flexible and practical end-to-end security with low overhead. System calls are used as synchronization points between the main core and DIFT coprocessor to prevent exploits while maintaining the DIFT security model. Experiments show the approach can detect various attacks without false positives in real-world applications and unmodified binaries.
SOURCE CODE ANALYSIS TO REMOVE SECURITY VULNERABILITIES IN JAVA SOCKET PROGRA...IJNSA Journal
This paper presents the source code analysis of a file reader server socket program (connection-oriented sockets) developed in Java, to illustrate the identification, impact analysis and solutions to remove five important software security vulnerabilities, which if left unattended could severely impact the server running the software and also the network hosting the server. The five vulnerabilities we study in this paper are: (1) Resource Injection, (2) Path Manipulation, (3) System Information Leak, (4) Denial of Service and (5) Unreleased Resource vulnerabilities. We analyze the reason why each of these vulnerabilities occur in the file reader server socket program, discuss the impact of leaving them unattended in the program, and propose solutions to remove each of these vulnerabilities from the program. We also analyze any potential performance tradeoffs (such as increase in code size and loss of features) that could arise while incorporating the proposed solutions on the server program. The proposed solutions are very generic in nature, and can be suitably modified to correct any suchvulnerabilities in software developed in any other programming language. We use the Fortify Source Code Analyzer to conduct the source code analysis of the file reader server program, implemented on a Windows XP virtual machine with the standard J2SE v.7 development kit.
We have evolved an IT system that is ubiquitous and pervasive and integrated into most aspects of our lives. Many of us are working on 4th and 5th level refinements in efficiency and functionality. But, we stand on the shoulders of those who came before and this restricts our freedom of action. The prior work has left us with an ecosystem which is the living embodiment
of our state-of-the-art. While we work on integration, refinement, broader application and efficiency, the results must move seamlessly into the ecosystem. Fundamental concepts are
being researched in the lab and may rebuild the world we all live in, until that happens, we must work within the ecosystem.
This document proposes a Rational Unified Treatment approach for Web Application Vulnerability Assessment (WVA). It implements the Rational Unified Process (RUP) framework to iteratively identify vulnerabilities. The approach discovers assets, audits for risks and threats, exploits identified vulnerabilities, and provides mitigation steps. It was tested on a web application using the w3af security scanner. The results generated reports on discovered vulnerabilities in different formats to help secure the application.
This document discusses vulnerabilities in antivirus software. It begins by noting that over 165 vulnerabilities have been reported in antivirus software in the past 4 years according to the US National Vulnerability Database. It then examines why antivirus software is a target for attackers, including that users have blind faith in it and its error-prone nature in processing many file formats. The document outlines techniques used to find vulnerabilities, including source code audits, reverse engineering, and fuzzing. It also looks at exploiting found vulnerabilities, such as through weak permissions. The overall aim is to raise awareness of security issues in antivirus products.
10. sig free a signature free buffer overflow attack blockerakila_mano
SigFree is a signature-free method for blocking buffer overflow attacks targeting internet services. It works by detecting the presence of executable code in messages, which legitimate requests do not contain. SigFree analyzes messages using a novel "code abstraction" technique to distill possible instruction sequences and prune non-code data using data flow analysis. It then determines if instruction sequences exceed thresholds for the number of useful instructions or dependence degree to identify code. Experimental tests showed SigFree could block over 750 known attacks with few false positives and negligible latency for normal requests.
SigFree is a proposed signature-free method to detect and block code-injection buffer overflow attacks by analyzing software code security without virus signatures. It works as an application layer blocker between a protected server and firewall. SigFree distills all possible instruction sequences from request payloads and analyzes them using code abstraction techniques to determine if executable code is present, blocking the request if so. The authors claim SigFree can block new and unknown attacks, is transparent to servers, and has low maintenance costs, making it suitable for large-scale Internet deployment.

This summarizes a research paper about standardizing source code security audits. The paper proposes assembling literature on security audit techniques to promote standard methodology. It then presents a case study analyzing vulnerabilities in the Apache Traffic Server using two proprietary tools. The study examines potential issues, connects them to a standard taxonomy (CWE), and describes consequences of exploits. The paper concludes by reviewing other security case studies.
Vulnerability analysis involves discovering parts of a program's input that can be exploited by malicious users to drive the program into an insecure state. Potential vulnerabilities exist in locations with known weaknesses that are dependent on or influenced by user input and can be reached during program execution. Vulnerability analysis aims to identify exploitable vulnerabilities by examining the paths in a program's control flow graph that connect points where untrusted data can enter and vulnerable functions can be reached.

Devoid Web Application From SQL Injection AttackIJRESJOURNAL
ABSTRACT: The entire field of web based application is controlled by the internet. In every region, World Wide Web is hugely necessary. So, network assurance is badly assuring job for us. Several kind of attacker or application programmer is attempting to split the immunity of information and destroy the instruction composed in the database. The SQL Injection Attack is very large safety measure risk in that present day. The indicated attacks allow to attacker’ s unlimited access from the database or still authority of database those determine web based application. That manages conscious and secret records and put the injurious SQL query put to modify the expected function. Many database reviewer and theorist give distinct concept to avoid regarding SQL Injection Attack. But no one of the concept is completely adaptable to. This research introduces a latest framework to protecting web based application from the SQL Injection Attack. Introduced framework i.e. present in this research is based on two techniques known as SQM (SQL Query Monitor) and Sanitization Application. That is the two ways filter program which analyses the user query and generate a separate key for user before it is sent to the application server. Several aspects of SQL Injection Attack are also discussed in that research.
A hybrid model to detect malicious executablesUltraUploader
This document presents a hybrid model for detecting malicious executables that uses three types of features: binary n-grams extracted from executable files, assembly n-grams extracted from disassembled executables, and DLL function calls extracted from program headers. A classifier like SVM is trained on the combined "hybrid feature set" to distinguish between benign and malicious executables. The model achieves high detection accuracy and low false positive rates compared to other feature-based approaches.
SECURITY FOR DEVOPS DEPLOYMENT PROCESSES: DEFENSES, RISKS, RESEARCH DIRECTIONSijseajournal
DevOps is an emerging collection of software management practices intended to shorten time to market for
new software features and to reduce the risk of costly deployment errors. In this paper we examine the security implications of two of the key DevOps practices, automation of the deployment pipeline using a deployment toolchain and infrastructure-as-code to specify the environment of the eployed software. We focus on identifying what changes when an organization moves from manual deployments to DevOps
automated deployment processes.We reviewed the literature and conducted three case studies using simple configurations of common DevOps tools. This allowed us to identify specific:
• Positive influences on security where automation enhances defenses.
• Negative influences, where automation enables different kinds of attacks and increases the attack
surface.
• Research directions that look promising to support this new approach to software management.
• Recommendations for DevOps adopters
A Platform for Application Risk IntelligenceCheckmarx
Using Source Code Understanding as a Risk Barometer:
Source Code Analysis technologies have significantly evolved in recent years – making improvements in precision and accuracy with the introduction of new analysis techniques like flow analysis.

This document analyzes LDAP injection techniques that can be used to exploit vulnerabilities in web applications that use LDAP directories. It discusses two types of LDAP injection - classic and blind. Classic injection allows attackers to directly execute malicious queries by appending injected code that will be processed by the LDAP server. Blind injection uses a binary approach to infer information from the server response without error messages. The document examines real examples of how attackers can use injected queries to view restricted documents or obtain a full list of users from the LDAP directory. It emphasizes that input validation is needed to prevent both classic and blind LDAP injection attacks.
The document introduces LLVM and its intermediate representation (IR) for program analysis. It describes how LLVM IR uses static single assignment form and three-address code.

Abstract:
""Enterprise Java" is a term we hear daily. However, how many of us actually--empirically--know what that represents from a risk, threat, and exposure basis? From the asset(s) it's on and data it accesses to the enterprise at-large that it sits within. This talk will explore the size, scope, and omnipresence of "Enterprise Java" in all its forms; and seek to give it a quantifiable attack surface. This talk will encompass various exemplars of where Enterprise Java appears in the enterprise. From the overt and ubiquitous application servers to the not so overt (but still ubiquitous) use in network appliances and "devices" (IoT) emerging today; and what this means to the threat profiles and attack surfaces of your organization."

Peter is the Network Security Manager for a small spare parts business. The organisation uses an e-sales application to provide a front-end for its e-sales business. Customers are complaining that in the last two or three days the system has become very slow, taking them longer than normal to place their orders. This information has been corroborated by staff complaining that they are not happy with the slow response of the system to complete their daily activities. Peter suspects that the system has been the target of criminal hands and before he starts responding to the attack, he decides to investigate the issue a little further. First, he reviews the firewall logs and notices something abnormal in the type of traffic directed to a number of internal hosts including the organisation’s web server. Curious about this traffic, Peter uses Wireshark to capture a trace of the traffic. [A section of this trace can be accessed from the course Moodle web site].

Effective Information Flow Control as a Service: EIFCaaSIRJET Journal
This document presents a framework called Effective Information Flow Control as a Service (EIFCaaS) to detect vulnerabilities in Software as a Service (SaaS) applications in cloud computing environments. EIFCaaS analyzes application bytecode using static taint analysis to identify insecure information flows that could violate data confidentiality or integrity. The framework consists of four main components: a model generator, an information flow control engine, a vulnerability detector, and a result publisher. The framework was implemented as a prototype and evaluated on six open source applications, detecting SQL injection and NoSQL injection vulnerabilities. EIFCaaS aims to provide third-party security analysis and monitoring of SaaS applications as a cloud-based service.
Aspect Oriented Programming Through C#.NETWaqas Tariq
.NET architecture was introduced by Microsoft as a new software development environment based on components. This architecture permits for effortless integration of classical distributed programming paradigms with Web computing. .NET describes a type structure and introduces ideas such as component, objects and interface which form the vital foundation for distributed component-based software development. Just as other component frameworks, .NET largely puts more emphasis on functional aspects of components. Non-functional interfaces including CPU usage, memory usage, fault tolerance and security issues are however not presently implemented in .NET’s constituent interfaces. These attributes are vital for developing dependable distributed applications capable of exhibiting consistent behavior and withstanding faults.

Question 1 (5 marks)
Note: for this question, you need to download a PCAP file located in the course Moodle web site.
Peter is the Network Security Manager for a small spare parts business. The organisation uses an e-sales application to provide a front-end for its e-sales business. Customers are complaining that in the last two or three days the system has become very slow, taking them longer than normal to place their orders. This information has been corroborated by staff complaining that they are not happy with the slow response of the system to complete their daily activities. Peter suspects that the system has been the target of criminal hands and before he starts responding to the attack, he decides to investigate the issue a little further. First, he reviews the firewall logs and notices something abnormal in the type of traffic directed to a number of internal hosts including the organisation’s web server. Curious about this traffic, Peter uses Wireshark to capture a trace of the traffic. [A section of this trace can be accessed from the course Moodle web site].
Based on the above fictional scenario and the provided PCAP:

Effective Information Flow Control as a Service: EIFCaaSIRJET Journal
This document presents a framework called Effective Information Flow Control as a Service (EIFCaaS) to detect vulnerabilities in Software as a Service (SaaS) applications in cloud computing environments. EIFCaaS analyzes application bytecode using static taint analysis to identify insecure information flows that could violate data confidentiality or integrity. The framework consists of four main components: a model generator, an information flow control engine, a vulnerability detector, and a result publisher. The framework was implemented as a prototype and evaluated on six open source applications, detecting SQL injection and NoSQL injection vulnerabilities. EIFCaaS aims to provide third-party security analysis and monitoring of SaaS applications as a cloud-based service.
Aspect Oriented Programming Through C#.NETWaqas Tariq
.NET architecture was introduced by Microsoft as a new software development environment based on components. This architecture permits for effortless integration of classical distributed programming paradigms with Web computing. .NET describes a type structure and introduces ideas such as component, objects and interface which form the vital foundation for distributed component-based software development. Just as other component frameworks, .NET largely puts more emphasis on functional aspects of components. Non-functional interfaces including CPU usage, memory usage, fault tolerance and security issues are however not presently implemented in .NET’s constituent interfaces. These attributes are vital for developing dependable distributed applications capable of exhibiting consistent behavior and withstanding faults.
This document provides a summary of Appaji Koppula's professional experience, including his current role as a Senior Software Development Engineer at Cisco Systems since January 2013. It also outlines his previous roles at Citrix R&D India, Juniper Networks, and Intoto Software, with descriptions of some representative projects he worked on in each role. These projects involved areas such as routing, virtual private networks, intrusion detection, and domain name resolution.

ABSTRACT
The J'BaFofi, or "Giant Spider," is a mainly legendary arachnid by reportedly inhabiting the dense rain forests of
the Congo. As despite numerous anecdotal accounts and cultural references, the scientific validation remains more elusive.
My study aims to proper evaluate the existence of the J'BaFofi through the analysis of historical reports,indigenous
testimonies and modern exploration efforts.
Mechanics:- Simple and Compound PendulumPravinHudge1
a compound pendulum is a physical system with a more complex structure than a simple pendulum, incorporating its mass distribution and dimensions into its oscillatory motion around a fixed axis. Understanding its dynamics involves principles of rotational mechanics and the interplay between gravitational potential energy and kinetic energy. Compound pendulums are used in various scientific and engineering applications, such as seismology for measuring earthquakes, in clocks to maintain accurate timekeeping, and in mechanical systems to study oscillatory motion dynamics.

Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

Mapping the Growth of Supermassive Black Holes as a Function of Galaxy Stella...Sérgio Sacani
The growth of supermassive black holes is strongly linked to their galaxies. It has been shown that the population
mean black hole accretion rate (BHAR) primarily correlates with the galaxy stellar mass (Må) and redshift for the
general galaxy population. This work aims to provide the best measurements of BHAR as a function of Må and
redshift over ranges of 109.5 < Må < 1012 Me and z < 4. We compile an unprecedentedly large sample with 8000
active galactic nuclei (AGNs) and 1.3 million normal galaxies from nine high-quality survey fields following a
wedding cake design. We further develop a semiparametric Bayesian method that can reasonably estimate BHAR
and the corresponding uncertainties, even for sparsely populated regions in the parameter space. BHAR is
constrained by X-ray surveys sampling the AGN accretion power and UV-to-infrared multiwavelength surveys
sampling the galaxy population. Our results can independently predict the X-ray luminosity function (XLF) from
the galaxy stellar mass function (SMF), and the prediction is consistent with the observed XLF. We also try adding
external constraints from the observed SMF and XLF. We further measure BHAR for star-forming and quiescent
galaxies and show that star-forming BHAR is generally larger than or at least comparable to the quiescent BHAR.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...Sérgio Sacani
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

4. ABSTRACT
There are many frameworks released every year and a
well designed framework may help developers create
secure web applications.
Cross-Site Request Forgery (CSRF) is among the oldest
web vulnerabilities that, despite its popularity and
severity, it is still an understudied security problem.
So here we will create and analyze open source
application and identified the percentage of protected
application for each framework.
5. INTRODUCTION
Here, we decided to study how
CSRF protection is implemented in
popular frameworks and to analyze
how the different levels of
mitigation control implementation
affect the security of applications
developed with those frameworks.

8. PAPER 1
CSRF protection in JavaScript frameworks
and the security of JavaScript
applications. [1]
• Published in High-Confidence Computing on December 2021
9. PROBLEM STATEMENT
● JavaScript frameworks are released every year and
we don’t know how cross-site request forgery
vulnerability is mitigated in several server- side
JavaScript frameworks.
10. WHY JAVASCRIPT
It’s because according to StackOverflow Developer Survey of 2021, JavaScript is named ”the
most commonly used programming language” for the ninth year in a row. [1]
11. Security Levels
● L0 - No mitigation in place. This provides a base case of lack
of any protection.
● L1 - Custom function that is written by developers and is
included in their own code
● L2 - An external library that provides a sanitization function
● L3 - A framework plugin , similar to an external library, that is
a third- party code used by developers.
● L4 - Built-in mitigation control , that is implemented in the
framework as a function or feature
12. Frameworks and Libraries
We selected four JavaScript
frameworks based on their
popularity
Express
For CSRF protection, there are two
popular plugins: csrf and csurf
Koa
The most commonly used for CSRF
protection is the koa-csrf plugin
01
02
03
04
05
Hapi.js
The crumb plugin implements CSRF
protection with the double-submit
cookie technique
Sails.js
Sails has several built-in security
features. And one of such security
features is CSRF protection.
Meteor.js
No HTTP only Distributed Data
Protocol (DDP), To maintain
sessions it store session token in
the LS instead of a cookie.
13. EXPRESS
For CSRF protection there are two popular plugins: csrf and csurf in
Express, csurf middleware builds on top of the csrf middleware and it
provides protection at level L3.
Fig:1.1 Express [1]
14. Koa
The most commonly used for CSRF protection is the koa-csrf plugin in Koa. It
is used globally, and the token can be submitted in the request body, as a
query parameter, or as an HTTP header. The koa-csrf plugin implements the
CSRF security control at level L3.
Fig: 1.2 Koa [1]
15. Hapi.js
The most common plugin for CSRF protection is crumb and it implements
CSRF protection with the double-submit cookie technique. Thus, similar to
Express and Koa, the Hapi framework provides the CSRF security control with
the crumb plugin at mitigation level L3.
Fig:1.3 Hapi [1]
16. Sails.js
Sails has several built-in security features which are configured as policies
and implemented as middleware functions. One of such security features is
CSRF protection. Therefore, it implements the CSRF protection at level L4
Fig: 1.4 Sails [1]
17. Meteor.js
Meteor.js use Distributed Data Protocol (DDP) Instead of sending traditional
HTTP requests, to exchange data between the server and the client.
To maintain sessions, Meteor stores a session to- ken in the local-Storage
instead of a cookie, which is used to establish a long-lived WebSocket
connection.
it implements the CSRF protection at level L5 - Architecture-level mitigation
control.
20. FUTURE WORK
Most of javascript library which use plugins for CSRF
protection, they provide L3 level security but we can
improve it to L4.

Deemon is the first research tool
that automatically detects CSRF
vulnerabilities but it works for PHP
only and but previous research
highlighted that existing web
application scanners are not
effective in this task.
28. HTTP REQUEST CLASSIFICATION
Structural is the category of features describes
structural properties of an HTTP request.
numerical features
• numOfParams
• numOfBools
• numOfBlobs
• reqLen
29. HTTP REQUEST CLASSIFICATION
● The average number of parameters of sensitive requests is around 6.27, while for
insensitive ones this is 3.43.
● it is evident that the median value of numOfParams is significantly higher for
sensitive than for insensitive HTTP requests.
Fig: 3.1 - Distribution of numOfParam [3]
30. HTTP REQUEST CLASSIFICATION
● This figure suggests that the length of sensitive requests is somewhat
more consistent and bounded within a smaller range of generally higher
values.
Fig: 3.2 - Distribution of reqLen [3]
31. HTTP REQUEST CLASSIFICATION
● Here this is distribution of the two features isGET and isPOST across sensitive and
insensitive requests.
● We observe that about 30% of POST requests are labeled as sensitive, while only
5% of GET requests are sensitive.
Fig: 3.3 - Distribution of class labels across the two functional
features [3]
32. Feature Importance
● we use the importance score as provided by the scikit-learn package, which in turn
implements it using Gini impurity Here is the top- 10 most important features
derived from our RF classifier.
● We can observe that the two most important features are and numOfParams,
followed by the two features reqLen encoding the request method.
Fig: 3.4 - Top10 most important features derived from
our RF [3]
33. CSRF Detection Algorithm
● the algorithm works by first building a set of candidate vulnerabilities,
based on sensitive requests which produce dissimilar responses.
Fig: 3.5 - Algorithm 1 CSRF Detection Algorithm [3]
34. SOLUTION
● Adversarial learning is an active research area whose main goal is designing
classification algorithms which are robust to the presence of attackers who actively
try to fool them into misprediction
Fig: 3.6 Mitch architecture[3]
35. FUTURE WORK
● There are a number of avenues for future work. Adversarial
learning is an active research area whose main goal is
designing classification algorithms which are robust to the
presence of attackers who actively try to fool them into
misprediction

Detection: The Case of Cross-Site
Request Forgery
• Published in Elsevier Microprocessor and Microsystems
journal, Volume 80, Article 103615, February 2021
37. PROBLEM STATEMENT
● For automated CSRF prevention SameSite cookie attribute
can be used to prevent cookie attachment on cross-site
requests.
● Unfortunately, this defense is not yet widespread.
38. SOLUTION
supervised learning automatically train a classifier which
partitions selected web objects of interest, e.g. HTTP
requests, HTTP responses or cookies, based on the web
application semantics. For example, in the case of CSRF
detection, the classifier would be used to identify security-
sensitive HTTP requests.

58. Cross-Site Request Forgery (CSRF) is one of
the oldest and simplest attacks on the Web,
yet it is still effective on many websites and it
can lead to severe consequences, such as
economic losses and account takeovers.
Unfortunately, tools and techniques
proposed so far to identify CSRF
vulnerabilities either need manual reviewing
by human experts or assume the availability
of the source code of the web application.
