Application Security - Your Success Depends on itWSO2
Traditional information security mainly revolves around network and operating system (OS) level protection. Regardless of the level of security guarding those aspects, the system can be penetrated and the entire deployment can be brought down if your application's security isn't taken into serious consideration. Information security should ideally start at the application level, before network and OS level security is ensured. To achieve this, security needs to be integrated into the application at the software development phase.
In this session, Dulanja will discuss the following:
The importance of application security - why network and OS security is insufficient.
Challenges in securing your application.
Making security part of the development lifecycle.
Secure web programming plus end users' awareness are the last line of defense against attacks targeted at the corporate systems, particularly web applications, in the era of world-wide web.
Most web application attacks occur through Cross Site Scripting (XSS), and SQL Injection. On the other hand, most web application vulnerabilities arise from weak coding with failure to properly validate users' input, and failure to properly sanitize output while displaying the data to the visitors.
The literature also confirms the following web application weaknesses in 2010: 26% improper output handling, 22% improper input handling, and 15% insufficient authentication, and others.
Abdul Rahman Sherzad, lecturer at Computer Science Faculty of Herat University, and Ph.D. student at Technical University of Berlin gave a presentation at 12th IT conference on Higher Education for Afghanistan in MoHE, and then conducted a seminar at Hariwa Institute of Higher Education in Herat, Afghanistan introducing web application security threats by demonstrating the security problems that exist in corporate systems with a strong emphasis on secure development. Major security vulnerabilities, secure design and coding best practices when designing and developing web-based applications were covered.
The main objective of the presentation was raising awareness about the problems that might occur in web-application systems, as well as secure coding practices and principles. The presentation's aims were to build security awareness for web applications, to discuss the threat landscape and the controls users should use during the software development lifecycle, to introduce attack methods, to discuss approaches for discovering security vulnerabilities, and finally to discuss the basics of secure web development techniques and principles.
The Zero Trust Model of Information Security Tripwire
In today’s IT threat landscape, the attacker might just as easily be over the cubicle wall as in another country. In the past, organizations have been content to use a trust and verify approach to information security, but that’s not working as threats from malicious insiders represent the most risk to organizations. Listen in as John Kindervag, Forrester Senior Analyst, explains why it’s not working and what you can do to address this IT security shortcoming.
In this webcast, you’ll hear:
Examples of major data breaches that originated from within the organization
Why it’s cheaper to invest in proactive breach prevention—even when the organization hasn’t been breached
What’s broken about the traditional trust and verify model of information security
About a new model for information security that works—the zero-trust model
Immediate and long-term activities to move organizations from the "trust and verify" model to the "verify and never trust" model
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

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

29. A1:2017- Injection
29
injection flaws, such as SQL, OS, XXE, and LDAP injection occur when untrusted data is sent to
an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter
into executing unintended commands or accessing data without proper authorization.
37. A2 Broken Authentication
37
Broken Authentication : Application functions related to authentication and session
management are often implemented incorrectly, allowing attackers to compromise
passwords, keys, or session tokens, or to exploit other implementation flaws to assume
other users’ identities temporarily or permanently
44. A3 Sensitive Data Exposure
44
“Sensitive data exposure : Sensitive data exposure vulnerabilities can occur when an application does
not adequately protect sensitive information from being disclosed to attackers. For many applications this
may be limited to information such as passwords, but it can also include information such as credit card
data, session tokens, or other authentication credentials.”
47. A4-XML External Entities (XXE)
47
Many older or poorly configured XML processors evaluate external entity references within XML
documents. External entities can be used to disclose internal files using the file URI handler,
internal file shares, internal port scanning, remote code execution, and denial of service attacks.
51. A5 : Broken Access Control
51
Access control : determines whether the
user is allowed to carry out the action that they
are attempting to perform.
authorization : the idea that, depending on
your role, you should have access to specific
things and be able to perform specific actions
be divided into the following
categories:
• Vertical access controls
• If a user can gain access to functionality
that they are not permitted to access then
this is vertical privilege escalation
• Horizontal access controls
• arises when a user is able to gain access to
resources belonging to another user
52. A5 : Broken Access Control
52
Normal users
Broken Access control
Admin
53. Demo -Insecure direct object references (IDOR)
53
subcategory of access control vulnerabilities. IDOR arises when an application uses user-supplied
input to access objects directly and an attacker can modify the input to obtain unauthorized access
54. A6 Security Misconfiguration
54
Software development life cycle :
Security Misconfiguration occurs when a system is configured in a way that makes it vulnerable
Ex:
• Default system credentials: user accounts, passwords in factory default or unchanged status
• Directory and file listings: not disabled and easily available through search engines
• User traces: pages returned to users with error messages that have too much information in
them
• Unnecessary pages: sample apps, old privileges, and user accounts, for example
• Software: not up-to-date, legacy systems, patches not utilized
56. A7:2017-Cross-Site Scripting (XSS)
56
“XSS flaws occur whenever an application includes untrusted data in a new web page without
proper validation or escaping, or updates an existing web page with user supplied data using a
browser API that can create JavaScript. XSS allows attackers to execute scripts in the victim’s
browser which can hijack user sessions, deface web sites, or redirect the user to malicious sites. ”
61. 61
Demo2 Google XSS Game
• <script>alert(document.cookie)</script> reflected xss
• <img src=x onerror="alert("CAT Reloaded")"> stored xss
• x' onerror="alert('CAT Reloaded')“ OR 3'><script>alert("CAT Reloade")</script>
62. A8 Insecure Deserialization
62
allows attackers to transfer a payload using serialized objects. This happens when integrity
checks are not in place and deserialized data is not sanitized or validated
This conversion is called serialization. Serialization is the process of taking an object and translating
it into plaintext. This plaintext can then be encrypted or signed, as well as simply used the way it is.
The reverse process is called deserialization, i.e. when the plaintext is converted back to an object.
a:4:{i:0;i:132;i:1;s:7:"Mallory";i:2;s:4:"user"; i:3;s:32:"b6a8b3bea87fe0e05022f8f3c88bc960";}
An attacker changes the serialized object to give themselves admin privileges:
a:4:{i:0;i:1;i:1;s:5:"Alice";i:2;s:5:"admin"; i:3;s:32:"b6a8b3bea87fe0e05022f8f3c88bc960";}
