bypassing authentication, and code execution. Conducting a series of methodical and repeatable tests and going through all the different application vulnerabilities is the best way to perform penetration testing. Web application pen testing is required due to the following reasons: The ports are scanned in order to identify the associated running Identification of ports: services and perform automated or manual tests to analyze the services and find weaknesses. Verification of vulnerabilities: The issue is tested and fixed to exploit the vulnerability. Remediation of vulnerabilities: The solution is retested against vulnerability to ensure that it is completely secure. ACL Access control list (ACL) is a rule list containing access control entries. It is used to allow or deny access to network resources. ACL can be implemented on network users and network devices such as routers and firewalls. Routers and firewalls use ACL to determine which packets should be forwarded or dropped. Steps in Web application testing In Web application penetration testing, a Penetration Tester needs to take the following steps: Information gathering testing Analyzing the robots.txt file Performing search engine reconnaissance Identifying application entry points Identifying Web applications Analyzing the output from head and options http requests Implementing techniques such as DNS zone transfers, DNS inverse queries, DNS searches, and querying search engines Analyzing error codes Testing for recognized file types/extensions/directories Examining source of available pages TCP/ICMP and service fingerprint Authentication testing Testing for vulnerable remember pw and pw reset Testing for logout and browser cache management Testing for captcha Testing for multiple factors authentication Testing for race conditions Session management testing Testing for session management using cookie tampering that results in hijacking the sessions of legitimate users Testing for cookie attributes to hijack sessions using tools such as Webscarab, Burp, Paros, and Tamper
