Tips For Successful Penetration Testing

Penetration testing is an important step while evaluating the security of a corporate network. It involves simulating a hacking attack on the network with an aim to breach its security and gain access to the confidential data. This helps IT professionals to determine the potential vulnerabilities that can be exploited by the hackers and how they can be fixed. However, carrying out an efficient penetration testing requires a lot of research and in-depth technical knowledge.

Given below are some steps that need to be followed for successful penetration testing:

Perform A Thorough Analysis

Firstly, you should have a clear idea about all the physical and intellectual assets of your company that you want to protect. Assess your network inside-out to determine the elements that are more susceptible to an attack and can severely hamper the functioning of your organization. Also, review your security policies to ensure that the penetration testing team is not able to get into the network.

Conduct A Pilot Study

Before initiating the penetration testing process, consider performing a pilot study on a small portion of the organization’s resources. This will help to identify the type of problems being faced and if any additional training or knowledge is required to deal with them. A pilot study will also allow the team to plan and structure the large scale penetration testing.

Choose A Penetration Testing Method

The next step is to select the most suitable method for conducting the penetration testing. Typically, you can choose from black box or white box tests. The former one involves initiating the attack without any prior knowledge of the company’s security systems and unpatched vulnerabilities. In a white box test, on the other hand, the tester has access to the sensitive information, such as network diagrams, IP addresses, source code etc.

Determine Who Will Perform The Test

This involves creating a strategy for the test. Determine who will perform the penetration test, an in-house team or an outsourced one. If the test involves the use of social engineering techniques, decide on the type of email that will be formulated and which employees will be the targeted. Create an information security incident response team who will stay updated with the penetration testing and ensure objectivity of the results.

Ways To Secure Your Network Infrastructure

Maintaining a secure network infrastructure is one of the major challenges faced by IT security professionals. All the hardware and software components are critical for seamless connectivity, communication, operations and management of the network. However, the rise of Bring Your Own Device (BYOD) culture and cloud computing resources has made it even more important to protect your company’s information as well as assets.

Given below are some of the tips that can help to secure your network infrastructure:

Understand your network design

First and foremost, you need to understand how the network infrastructure at your organization functions. Gain knowledge about the devices that are connected to the network and the points through which data is transmitted between them. 

Review all the applications

The applications and programs installed on your organization’s computer systems can provide a backdoor for the hackers to gain unauthorized access. Undetected malware, viruses and Trojans can make the entire corporate network vulnerable to various hacking attacks. Hence, it is essential to constantly review all your applications and software programs to ensure that they are completely secured.

Build a security culture

Provide proper IT security training to your employees and set clear guidelines regarding safe usage of the infrastructure. Make them familiar with the common online threats and what should be done to stay protected. This will create a strong security culture and help employees understand their responsibilities towards protecting the company’s resources.

Use secure socket layer

A secure socket layer (SSL) can add a layer of protection to your network infrastructure. It encrypts all the information while it is being transmitted between a user and the web browser. This ensures that the information being shared within your corporate network is not read, manipulated or used by any unauthorized individual.

Avoid adding complexity to your network infrastructure

Unless it is absolutely necessary for the optimal functioning of your organization, do not complicate your network infrastructure. Adding superfluous devices, servers, wireless endpoints etc. increases the chances of your network getting compromised. In case you need to add a network service, ensure that it is properly secured. This, way, even in the event of a breach, the functioning of your entire network will not be jeopardized.

Fundamental Tips To Keep Your Network Safe

IT security is a pre-requisite for successful business operations. The present day online attacks are very sophisticated, hard to detect and can cause serious damage to the computers on your corporate network. Besides malware and virus infection, there are many other security threats, such as Denial of Service (DoS), spyware, ransomware, man-in-the-middle attack etc. Therefore, regardless of the size and type of your organization, it is important to take the necessary network security steps to protect your data from cybercriminals.

Discussed below are a few fundamental tips to keep your network safe:

Delete Unused Accounts

Email or social networking accounts that are not active should be deleted. Since these accounts do not have updated security settings, they are quite easy to be hacked. Make sure you timely review all your official accounts and identify as well as delete the ones that are no longer required. You can either perform this task manually or use a software to remove unused accounts.

Keep VPN Secured

If you use a virtual private network (VPN), you should keep it completely secure to prevent unauthorized access to your company’s internal network. Use the most advanced authentication and encryption protocols to monitor as well as regulate the network’s usage. You can even consider accessing the internet remotely so that your browsing details are not saved.

Be Proactive With System Updates

Cybercriminals are always on the lookout for security flaws in obsolete web browsers, plug-ins, software applications and operating systems that can be exploited for malicious purposes. It is therefore, important to update all the computer systems on your network on a regular basis. Software vendors frequently release patches and updates to fix the bugs as well as improve functionality of the applications. The IT staff should either enable automatic updates or download and install the latest versions from trusted sources.

Secure Your Router

Make sure that you change the default name and password of your router. The default credentials are quite common and can easily be decoded by the hackers. Create a strong and lengthy password as well as a unique username. Also, change the security level from WEP (Wired Equivalent Privacy) to WPA (Wi-Fi Protected Access) or WPA2 so that only the authorized users have access to the corporate network.

Types Of Network Attacks

Network attack can be defined as an attempt to breach the security of a computer network in order to gain unauthorized access to the targeted device or exploit the vulnerabilities in the software applications. Without proper security measures, your network is vulnerable to different types of security threats, eventually causing it to crash. A network attack can either be passive (wherein the hacker may simply monitor and steal data stored on the computer) or passive (in which the information may be altered or destroyed).

Given below are some of the common types of network attacks:

IP Spoofing

A corporate or home network uses the IP address of a device to identify its entity and allow access. In a spoofing attack, the hacker may use a forged IP address to breach into a network in the guise of a legitimate user. He may alter, delete or destroy the data being shared in the network. He may also modify the source of the data packets so that they appear to be originating from another computer on the same network.

Sniffing

Network sniffing is the process of monitoring, capturing and intercepting the data packets traveling through an internet network. If the data is not properly encrypted and sent as cleartext, it can be easily read by the hacker. On the other hand, an encrypted data packet cannot be accessed unless the hacker has the key to open it.

Buffer Overflow

A buffer overflow attack occurs when the target computer receives more data/traffic than it is capable to hold, thus creating a lot of temporary files that overwrite the already existing valid data. The excess files usually contain a malicious code designed to carry out specific actions, such as deleting files, altering data or transmitting confidential information to the hacker.

Man In The Middle Attack

This is a form of session hijacking attack in which the hacker actively monitors, captures and controls the flow of information between the source as well as the destination computer on a network. The attack may be simply aimed at getting access to the information being shared or modifying it before being transmitted to the other end. In some forms of man in the middle attacks, the hacker may even disconnect the other user and completely take over the session to acquire sensitive information.
