What are the Cyber Security tool and Techniques

Last Updated on

Cyber security is the preventative action of protecting computer systems, networks, and software from malicious attacks or unauthorized access.

To ensure the IT security of an organization cyber security tool are very important. Cyber security is the protection of computer systems and network from cyber-attack. However, the most important security tools and techniques of cyber security are as follows:

1.  Firewall

A firewall is network security tool which is designed to monitors incoming and outgoing network traffic and permits or blocks data packets based on security rules. Its main purpose is to create an obstacle between trusted internal network and untrusted external network in order to block malicious.

In addition, firewalls can be implemented as hardware and software based, or a combination of both.

It is designed to monitors incoming and outgoing network traffic

Software Based Firewall

A software-based firewall is a program which installed on individual servers and monitors incoming and outgoing traffic through port numbers and applications. It is easy to install, and no additional hardware is required.

Hardware Based Firewall

Hardware based firewalls are built into the network routers which is designed to protect all the devices connected to a network.

A hardware firewall uses packet filtering to examine the header of a packet to determine its source and destination address. This information is compared to a set of predefined rules to determine whether the packet is to be forwarded or dropped.

Types of Firewalls

There are five different types of firewall which are as follows:

  • Packet filtering Firewalls
  • Stateful inspection Firewalls
  • Circuit level gateway Firewalls
  • Proxy Firewalls and
  • Next-generation Firewalls (NGFWs)

2.  SSL Certificate

SSL stands for Secure Sockets Layer is a global standard security protocol which establishes a secure connection between a web server and browser.

It ensuring that all data passed between a web server and browser remains encrypted and secure. This encryption technique prevents hackers from stealing sensitive information such as credit card details, names and addresses.

In the case of a browser, if a site is secure by SSL then a padlock is displayed or the address bar shows the URL as HTTPS instead of HTTP.

Types of SSL Certificates

There are different types of SSL certificates available in the market today, which are as follows:

  • Organization Validated (OV) SSL Certificates
  • Domain Validated (DV) SSL Certificates, and
  • Extended Validated (EV) SSL Certificates

3.  Antivirus Software

Antivirus software is a security tools which designed to search, detect, and remove malicious software or programs like worms, trojans, spam, adware etc. from computer.

However, the main objective of antivirus program is to protect computers and remove viruses once detected.

There are different types of anti-virus software in market based on the OS compatibility, which are as follows:

  • Antivirus for Windows OS
  • Antivirus for Linux OS
  • Antivirus for Android OS
  • Antivirus for MAC OS

4.  Web application firewall

A web application firewall or WAF is an application based cyber security tool. It is designed to protect applications, APIs, and mobile apps by filtering and monitoring HTTP harmful traffic between a web application and the internet.

Application firewall typically protects web applications from different types of attacks such as cross-site-scripting (XSS), file inclusion, SQL injection, Session hijacking, Layer 7 DoS and others.

A WAF can be implemented one of three different ways such as Network-based WAFs, Host-based WAFs  and Cloud-hosted WAFs

5.  Cyberoam Unified threat Management (UTM)

Cyberoam firewall is Network Security appliances which is available as a Next-Generation Firewall and Unified threat management (UTM) firewall.

Cyberoam offers comprehensive network, web application and email security while providing secure remote access and data leakage prevention. It is a centralized Unified threat management system that enables organizations to implement and ensure high levels of cyber security with visibility across global locations.

It has the following features:

6.  Penetration Testing

Penetration testing is a very important cyber security tool and mechanism where a cyber-security expert attempts to evaluate the security of a system using controlled environment. Its main purpose is to identify security weaknesses, and exploit vulnerabilities of application.

These type of testing tools helps you to identifying security weaknesses and vulnerability of an application or in a network.

It is very useful because it allows identifying the “vulnerabilities” in the software and networking applications which can cause a security breach.

Here is a list of Penetration Testing Tools:

7.  Encryption

Encryption software is a type of security programs that enable encryption and decryption of a data stream during transmission and storage. It enables the encryption of the content of a data object, file, and network packet or application.

8.  Disaster recovery

Disaster recovery or DR is a set of security tools and procedures that focus on protecting an organization from any significant effects, which may include cyber-attacks and natural disasters.

It is part of security planning which is developed in conjunction with a business continuity plan.

DR measures can be classified mainly into three types which are as follows:

  • Preventive measures
  • Corrective measures
  • Detective measures

9.  Digital Signature

A digital signature is a another cyber security tool and mathematical technique which used to validate the authenticity and integrity of a digital messages or documents such as e-mail, spreadsheet, and text file. It uses encryption techniques and guarantees that the contents of a message have not been altered in transit.

Digital signatures use a standard, called Public Key Infrastructure (PKI) to provide the highest levels of security and global acceptance. This signatures are used in e-commerce, software distribution, and financial transactions.

PKI use two keys: One key is public, and one key is private.
