Abstract Types of Penetration Testing, Penetration Testing is an authorized proactive attempt to External Network Penetration Testing. measure the security of an IT system by safely exploiting The goal of the external network Penetration Testing is to. its vulnerabilities mostly to evaluate application flaws demonstrate the existence of known security vulnerabilities. improper configurations risky end user behavior Be that that could be exploited by an attacker as they appear outside. as it may why would you voluntarily perform a self hack in the perimeter of the network usually from the internet. the first place What are the different types of Penetration External testing involves analysis of publicly available infor. Testing What are the principal approaches methodolo mation a network enumeration phase and the behavior of the. gies tools techniques and the best practices of the security devices is analyzed It is the traditional approach to. same This whitepaper interestingly addresses the above Penetration Testing and it involves assessing the servers. concerns and throws light on this subject in more detail technology infrastructure and the underlying software com. prising the target It is performed with no prior knowledge of.

Non destructive,exploitation of,vulnerabilities,Result collation. and report writing, Profiling involves gathering as much as information as possible about the target network for discovering the possible ways to.
enter into the target organization This involves determining the target operation systems web server versions DNS informa. tion platforms running existence of vulnerabilities exploits for launching the attacks The information can be gathered using. various techniques such as Whois lookup enquiring the DNS entries google searches using GHDB social networking sites. emails websites etc,Discovery Enumeration, Discovery involves using the automated tools and manual techniques to identify the live hosts present in the network deter. mining the target system s operating system through banner grabbing presence of open ports services running versions. of the services technology information protocols and its version. Enumerating an internal network allows the penetration tester to identify the network resources shares users groupsus. ers groups routing tables audit serviceaudit service settings machine names applications bannersapplications. banners and protocols with its details The identified information would allow the Penetration tTester to identify system. attack points and perform password attacks to gain unauthorized access to informationsystems. Scanning involves identifying the vulnerabilities present in network services information systems and perimeter security. controls by enterprise class tools with most updated feeds and using the best manual scripts In addition manual assess. ments helps eliminating the false positives reported by the tools and to identify the false negatives. Scanning will identify network topology OS vulnerabilities application services vulnerabilities application services. configuration errors etc In the scanning phase the pPenetration tTester will identify exploits and evaluate attack surface. 4 Happiest Minds Technologies Pvt Ltd All Rights Reserved. Exploitation, This stage uses the information gathered on active ports and services with the related vulnerabilities to safely exploit the. services exposed Attack scenarios for production environment will use a combination of exploit payloads in strict accord. ance with agreed rules of engagement It involves research test exploits and launch payloads against the target environ. ment using Penetration tTest frameworks such as meta sploit. All exploitable security vulnerabilities in the target system are recorded with associated CVSS v2 based scores are reported. to the client The identified security vulnerability is thoroughly assessed and reported along with appropriate recommenda. tion or mitigation measures,Reference Testing for system takeover. Identifying and determine the status of vulnerable service on port 6667 on remote system.

The best practices and recommendations, The following are the best practices that could be followed in applying the defense in depth strategy across.
the internal network services, Establish technical standards for Systems Security Network Security device hardening. Security assessments to be integrated with change management processes to avoid introduction of. vulnerability in the technology environments, Patch and vulnerability management must be tracked closely with platform teams or system owners. Firewall configuration reviews and change management must be conducted periodically. Periodically conducted internal and external network security assessment that include compliance checks. against the build standards if package operating systems i e hardened builds are deployed across the. organization, Security benchmark can be found on center for internet security. 6 Happiest Minds Technologies Pvt Ltd All Rights Reserved.
