With organisations’ increased reliance on infocomm technology in their pursuit for competitive advantage, keeping the IT infrastructure safe should be one of the top priorities in organisations. Leaving security vulnerabilities unresolved and open for hackers to exploit can lead to severe monetary and reputation loss. Depending on the organisation’s intent – whether it is to find out the security vulnerabilities present in IT systems or to determine the security resiliency of the application, there are two approaches that organisations may adopt. Vulnerability Assessment is a non-intrusive approach that serves to produce a prioritised list of security vulnerabilities. A combination of automated and manual scan may be performed on the organisation’s IT systems or network, to identify flaws that may be exploited during an attack. The systematic approach of identifying, quantifying, and ranking security vulnerabilities enables organisation to select critical vulnerabilities to resolve based on their available resources. Without such assessments, there is a risk that IT infrastructure are not sufficiently secured. It is recommended that organisations should perform a vulnerability assessment on their IT infrastructure on a quarterly basis, and as well as to assess their applications on a yearly basis. Penetration Testing on the other hand, uses an intrusive approach to discover security weaknesses in the organisation’s IT infrastructure and applications. Penetration testers would attempt to exploit identified security weaknesses to gain privileged access into the IT infrastructure and applications. Such approach emulates a real attack, and would determine the robustness of the organisation’s IT infrastructure in protecting sensitive information. The difference between vulnerability assessment and penetration testing is that the former helps to discover the security loopholes present in organisation’s...
If you are considering having your network penetration tested then more than likely you with either go down the black box or white box route. Black Box Testing The main differences are that with black box texting the testers are given very little or no information prior to the penetration test. It is also referred to as “blind testing” because the tester has to find an open route to access the network. White Box Testing Is when the tester is given full disclosure about the network prior to the penetration testing. This will include IP addresses, source code, network protocols and diagrams. Also known as “Full Disclosure” testing. Grey Box Testing “Partial Disclosure Testing” In between black box and white box testing, you will find grey box penetration testing. The penetration tester will be given partial details about the network infrastructure. Pros & Cons of Back Box & White Box Testing In a black box penetration test the attacker will be unfamiliar with the network, which is generally more realistic to everyday penetration attacks or “hacks”. This will stimulate more accurate results, as they will not be privy to any additional information and would give you the most realistic indication of potential threats to your network. White Box penetration testing would indicate results if you had a threat from inside the network that was using knowledge of your network, such as IP addresses, router access, active ports, web servers, FTP, and even passwords. A black box tester would not have this information and usually unable to scan the network for threats as thoroughly. Vinova is providing affordable and...

Penetration testing (also called pen testing or pentest) is the practice of testing a computer system, network or Web application to find vulnerabilities that an attacker could exploit. Pen tests can be automated with software applications or they can be performed manually. Either way, the process includes gathering information about the target before the test (reconnaissance), identifying possible entry points, attempting to break in (either virtually or for real) and reporting back the findings. The main objective of penetration testing is to determine security weaknesses. A pen test can also be used to test an organization’s security policy compliance, its employees’ security awareness and the organization’s ability to identify and respond to security incidents. Penetration tests are sometimes called white hat attacks because, in a pen test, the good guys are attempting to break in. Pen test strategies include: Targeted testing Targeted testing is performed by the organization’s IT team and the penetration testing team working together. It’s sometimes referred to as a “lights-turned-on” approach because everyone can see the test being carried out. External testing This type of pen test targets a company’s externally visible servers or devices including domain name servers (DNS), e-mail servers, Web servers or firewalls. The objective is to find out if an outside attacker can get in and how far they can get in once they’ve gained access. Internal testing This test mimics an inside attack behind the firewall by an authorized user with standard access privileges....
