Network Security VAPT

What is network vapt?

VAPT is an acronym for Vulnerability Assessment and Penetration Testing. It’s a service by which corporate IT networks are scanned and tested for the presence of security loop holes. Leaving such loopholes can result into exploitation and hacking of the data, which should ideally be protected by the IT networks.

A detailed explanation of VAPT can be found here.

Some Facts

Firewall Invasions - 66%
Patching Vulnerabilities - 80%
External Hacking - 55%

Types of network vapt

At a high level, a network vulnerability assessment and penetration testing can be categorize into 2 different types.

Internal VA – In this, only the internal network is in scope. Internal servers, firewalls and data components such as database servers or file servers are of key importance from vulnerability scanning perspective. Since the test is to be performed from within the network, only vulnerability assessment is performed, while penetration testing is not performed. Internal security assessment can be performed by physically being inside the network premises or by performing a remote session into the network.

External VAPT – In this type, the external perimeter is scanned over internet. Since the testing occurs from outside the premises, the vulnerability assessment is certainly followed by a detailed penetration testing. In the former, the security bugs or problems are found out by vulnerability scanning while in the later, those bugs are tried for exploitation. Please refer to Links page for more information.

Besides this, there are multiple other types of VAPT which mainly focus on the network components such as firewall VAPT, Servers VAPT etc.

Why Network VAPT Is Done?

Network security testing is important for any corporate to protect their intellectual property. Most of the attacks being internal, it is imperative to scan the networks periodically and fix the loopholes. This helps corporates achieve a better cyber security posture of their IT corporate network, by protecting their data from internal and external threats.

As an example, consider a famous bank in India, which got hacked by hackers who stole money via ATM skimming. In other cases, many manufacturing companies get targeted malware attacks or their internal employees steal data and sell it for profits. Below are few facts which become the key driver to perform a VAPT of IT systems.

As per Gartner, 78% of attacks happen from within the network

External attacks become easily possible due to availability of hacking tools

Firewall mis-configurations are one major cause of data leakage and hackings

Server patching contributes into network security vulnerabilities to a great extent

Companies who should get VAPT done

While there cannot really be an exception to the industry sectors needing cyber security, below examples can demonstrate the real need of vulnerability assessment services. It is highly advised to get a VAPT done from one of the top cyber security companies, or best network security company.

  • IT product companies to protect their code and data
  • IT services companies to prevent external attacks
  • Manufacturing companies to protect their designs, drawings and inventory data
  • Finance companies to protect their finance data, secure money transactions and records
  • Pharma companies having their own patents about drug formulas and intellectual properties
  • All firms and corporates who process or store their data as well as data belonging to their customers

How frequently VAPT should be performed?

There is not definitive answer to this question. However a thumb rule says that more the sensitivity and criticality of the data, higher should be the frequency. Typically, organizations choose a 6 monthly cycle, while the finance sector chooses quarterly pentesting of their IT infrastructure. There had been cases whereby the data was so critical that the organizations chose to perform a weekly testing just to be very sure of their cyber security posture.

As another thumb rule, the frequency is directly proportional to the size of network, as well the hacking or data leakage incidents occurring within the organization. Any critical change in the network devices ideally calls for a VAPT of those components.

When to perform Network VAPT ?

Whenever there is a change in firewall configuration, server patching, application changes or addition/removal of IT infrastructure, a detailed vulnerability assessment is required to be performed. In many cases if the change is internal only, a vulnerability assessment is good enough.

For example – a change in entire firewall should call for a detailed VAPT to be performed internally and externally. Whereas a set of servers patched can call for an internal only vulnerability assessment. It is an art to decide when to perform vulnerability assessment only, and when to further go for a penetration testing.
