Security testing involves testing software to identify security flaws and vulnerabilities. It is done at various stages of development, including unit testing by developers, integrated system testing of the full application, and functional acceptance testing by quality assurance testers. Security testing techniques include static analysis, dynamic testing, and fuzzing invalid or random inputs to expose unexpected behaviors and potential vulnerabilities. Thorough security testing requires checking for issues like SQL injection, unauthorized access, disclosure of sensitive data, and verifying proper access controls, authentication, encryption, and input validation. Various tools can assist with security testing.
Security Testing is deemed successful when the below attributes of an application are intact
- Authentication
- Authorization
- Availability
- Confidentiality
- Integrity
- Non-Repudiation
Testing must start early to minimize defects and cost of quality. Security testing must start right from the Requirements Gathering phase to make sure that the quality of end-product is high.
This is to ensure that any intentional/unintentional unforeseen action does not halt or delay the system.

DevOpsCon 2016 - Continuous Security Testing - Stephan KapsStephan Kaps
Continuous Delivery (CD) ist in aller Munde. Zu Recht, doch wollen wir unsere Software kontinuierlich ausliefern, müssen wir auch kontinuierlich Sicherheitstests durchführen.
Continuous Security Testing bedeutet, statische und dynamische Analysen bereits während der Entwicklung durchzuführen, um frühzeitig und regelmäßig Sicherheitsmaßnahmen umzusetzen, bevor manuelle Prüfungen wie Penetrationstests zum Einsatz kommen. Um eine Anwendung bereits während der Entwicklung auf das Vorhandensein sicherheitskritischer Schwachstellen hin überprüfen zu können, ist eine Integration in den Entwicklungsprozess und somit eine kontinuierliche und am besten automatisierte Prüfung notwendig.
Der Vortrag stellt die praktischen Erfahrungen aus einem Projekt vor, bei dem Sicherheitsrichtlinien (Secure Coding Guide) für die eigene Entwicklung von Java-Webanwendungen aufgestellt und Sicherheitstests in den Softwareentwicklungsprozess integriert wurden. Dabei wird auf die organisatorischen, inhaltlichen und technischen Überlegungen eingegangen.

The OWASP Top Ten is an expert consensus of the most critical web application security threats. If properly understood, it is an invaluable framework to prioritize efforts and address flaws that expose your organization to attack.
This webcast series presents the OWASP Top 10 in an abridged format, interpreting the threats for you and providing actionable offensive and defensive best practices. It is ideal for all IT/development stakeholders that want to take a risk-based approach to Web application security.
How to Test for the OWASP Top Ten webcast focuses on tell tale markers of the OWASP Top Ten and techniques to hunt them down:
• Vulnerability anatomy – how they present themselves
• Analysis of vulnerability root cause and protection schemas
• Test procedures to validate susceptibility (or not) for each threat
In the ever-evolving, fast-paced Agile development world, application security has not scaled well. Incorporating application security and testing into the current development process is difficult, leading to incomplete tooling or unorthodox stoppages due to the required manual security assessments. Development teams are working with a backlog of stories—stories that are typically focused on features and functionality instead of security. Traditionally, security was viewed as a prevention of progress, but there are ways to incorporate security activities without hindering development. There are many types of security activities you can bake into your current development lifecycles—tooling, assessments, stories, scrums, iterative reviews, repo and bug tracking integrations—every organization has a unique solution and there are positives and negatives to each of them. In this slide deck, we go through the various solutions to help build security into the development process.
Penetration Testing actively attempts to exploit vulnerabilities and exposures in the customer environment. You can learn more about the value and the outcomes of this services.
# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks
Introduction to security implications while writing application code for public facing gateway services.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

30. Conclusion
Security testing is an important and integral part of the software developmental process.
You will need to conduct this test to find security loopholes and later close them with
appropriate security measures and techniques
Good morning, the pupose of this presentation is to introduce security testing
We will begin our presentation by an introduction, then we will present some security flaws as well as types and methods to test these flaws and we will finish by a conclusion
Testing is an important part of software development and it is vital to start it as early as possible, its objectives is to find flaws and vulnerabilities of a system
The database is a prime target for application level attacks. The top threats to data access code are:
SQL injection
Disclosure of configuration data
Disclosure of sensitive application data
Disclosure of database schema and connection details
Unauthorized access
Network eavesdropping
An SQL injection attack consists of insertion of either a partial or complete SQL query via the data input or transmitted from the client to the web application.
Common vulnerabilities that make your data access code susceptible to SQL injection attacks include:
To counter SQL injection attacks, be sure to:
For example, Let's say that the original purpose of the code was to create an SQL statement to select information about a user’s credit card,
The SQL above is valid. It will return all rows from the table CreditCard, since WHERE 1equal1 is always true
With inadequate authorization, users may be able to see another user's data and may be able to access other restricted data.
Practices that can allow unauthorized access include:
To prevent unauthorized access:
This example has four users. The users select from a set of resources such as Public Share, Time Card Entry and Account Manager.
Larry should not be allowed to access the Account Manager resource because Larry is not assigned to the required role. However in this example, Larry’s access is allowed in the application.
The main issue is that the application does not implement the access control correctly to verify whether the user Larry is authorized to access Account Manager resource.
The deployment architecture of most applications includes a physical separation of the data access code from the database server. As a result, sensitive data such as application-specific data or database login credentials must be protected from network eavesdroppers.
The following practices increase vulnerability to network eavesdropping:
To limit vulnerability to network eavesdropping:
As shown above, while transmitting a sensitive data through the network , attackers could steal that information,
Therefore we must secure our software, so how to test security software
Security testing is basically a type of software testing that’s done to check whether the application or the product is secured or not. It checks to see if the application is vulnerable to attacks, if anyone hack the system or login to the application without any authorization.
Unit test : test logic in classes by programmers to show code level correctness. They should be fast and not dependend on other parts of the system that you don't intend to test
Integration test : Test communication paths between different parts of the module done by the test department or by developers to show that all modules work correctly together.
Functional acceptance test : test use case scenario's on a limited (specially created) data set done by the test department to show that every specified scenario works as specified.
We can find also other types of security testing such as static, dynamic
Static test : it verifies the security of the software by analyzing either the source code or the compiled application without running the project
Dynamic test : it tests the software in the running mode
We can also find others method for testing software such as fuzzing test
Fuzzing is a method of testing software to find security holes and unexpected behavior of an application, using semirandom data.
The fuzzing process is defined as shown here, First, a generator produces test inputs. Second, the test inputs are delivered to the system under test. The delivery mechanism depends on the type of input that the system processes. Third, the system under test is monitored for crashes and other basic undesirable behavior. Also Reports describes the results of the test could be generated automatically
One can monitor the target application in many ways. Such as monitor for event logs, monitor application crashes using debuggers, monitor using tools of virtualization like vmware etc ,,,
application is tested by a previously prepared fuzzer. Test results are verified by testers. Next, they are sent to programmers. If any errors occur, programmers must fix the application. New build once again must pass the fuzzing process.
Some frameworks are used the fuzzing test such as Peach and sulley, peach can test virtually any system for unknown vulnerabilities. From common test targets to complex proprietary systems, Peach is the fuzzer for the job. The goal of the framework sulley is to simplify not only data representation but to simplify data transmission and target monitoring as well. There are some tools specialized fuzzers such as …
security test cases cheat list or check-list”, for example, can provide simple test cases and attack vectors that can be used by testers to validate exposure to common vulnerabilities,
Input validation is the correct testing of any input; we should verify the data is strongly typed, correct syntax, within length boundaries, contains only permitted characters, or that numbers are correctly signed and within range boundaries
Problems resulting from incorrect input validation :
Access control policies can be specified in programming languages or policy specification languages and implemented in a particular access control implementation. Policies need to be carefully designed and implemented to prevent data from unauthorized access, diclosure of sensitive data dos and ddos attacks etc
The Cryptography Policy sets out when and how encryption should (or should not) be used. It includes protection of personal, confidential and commercially sensitive information and communications, key management, and procedures to ensure encrypted information can be recovered by the organisation if necessary.
Authentication is the process of verification that an individual, entity or website is who it claims to be, Session Management is a process by which a server maintains the state of an entity interacting with it. Sessions are maintained on the server by a session identifier which can be passed back and forward between the client and server when transmitting and receiving requests. Sessions should be unique per user and computationally very difficult to predict
Limit access to data based on the least privilege principal. Encrypt sensitive data and information like stored passwords, connection strings and properly protect decryption keys. We should Make sure all cached or temporary copies of sensitive data are protected from unauthorized access and get purged as soon as they are no longer required,
When transmitting sensitive information, at any tier of the application or network architecture, encryption-in-transit should be used. We should Use a trusted certificate authority to generate public and private keys whenever possible. Moreover, proper security controls must be in place to protect the private keys from unauthorized access.
is one of the world’s most popular free security tools and is actively maintained by hundreds of international volunteers. It can help to automatically find security vulnerabilities in web applications while developing and testing the applications. Its also a great tool for experienced pentesters to use for manual security testing
Wfuzz is a tool designed for bruteforcing Web Applications, it can be used for finding resources not linked (directories, servlets, scripts, etc), bruteforce GET and POST parameters for checking different kind of injections (SQL, XSS, LDAP,etc), bruteforce Forms parameters (User/Password), Fuzzing,etc
Secure applications can ensure system safety and security. It can impede attacks by hackers. Security testing is one of the most important tests that you should conduct before introducing it to the commercial domain
