![]() If a vulnerable component is exploited, such an attack can facilitate serious data loss or server takeover. Components, such as libraries, frameworks, and other software modules, run with the same privileges as the application. Using Components with Known Vulnerabilities. Even if deserialization flaws do not result in remote code execution, they can be used to perform attacks, including replay attacks, injection attacks, and privilege escalation attacks. ![]() ![]() Insecure deserialization often leads to remote code execution. ![]() 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. 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 HTML or JavaScript. Not only must all operating systems, frameworks, libraries, and applications be securely configured, but they must be patched/upgraded in a timely fashion.Ĭross-Site Scripting XSS. This is commonly a result of insecure default configurations, incomplete or ad hoc configurations, open cloud storage, misconfigured HTTP headers, and verbose error messages containing sensitive information. Security misconfiguration is the most commonly seen issue. Attackers can exploit these flaws to access unauthorized functionality and/or data, such as access other users’ accounts, view sensitive files, modify other users’ data, change access rights, etc. Restrictions on what authenticated users are allowed to do are often not properly enforced. 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.īroken Access Control. Many older or poorly configured XML processors evaluate external entity references within XML documents. Sensitive data may be compromised without extra protection, such as encryption at rest or in transit, and requires special precautions when exchanged with the browser. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Many web applications and APIs do not properly protect sensitive data, such as financial, healthcare, and PII. 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. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization.īroken Authentication. Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when untrusted data is sent to an interpreter as part of a command or query. ![]() It has a clean, high-performance user interface with only the most relevant results and no telemetry, no ads and no collection of private information.Īccounting & Information Security and Risk Management, Asset Security, Security Engineering, Communication and Network Security, Identity and Access Management, Security Assessment and Testing, Security Operations, and Software Development Security. With results augmented by non-commercial indexes and personalized searches. Shishi.ng Search is a quick, user-centric, 100% privacy-respecting search engine For Africa specific to Nigeria. Then you have questions about availability vs confidentiality vs integrity and this is the CIA perspective, while a question about the annual loss expectancy (ALE) is related to risk management. If you get a question about symmetric vs asymmetric encryption, then that’s the technology perspective and the question is testing your technical knowledge.Ī question about the company’s best approach for security, is challenging your management perspective, and here you should put your self in the place of a security manager and think how would a security manager act in the situation. Risk: risk management which is very important topic in the examĮvery time you see a CISSP question, you should be able to look it from one of those perspectives or frameworks. Management: what is the best approach to do something from a security manager’s perspective? A good way to look at the CISSP exam is to view in through the lens of four different frameworks:ĬIA: Confidentiality, Integrity and Availability. ![]()
