IT Security

IT security refers to a collection of cybersecurity strategies implemented to prevent unauthorised access to organisational assets, including computers, networks, and data. It also ensures the confidentiality and integrity of sensitive information while blocking the access of sophisticated hackers.

Types of IT Security

Network security:

This strategy prevents unauthorised or malicious users from accessing the network. It helps maintain usability, reliability, and integrity. Network security is crucial in preventing hackers from accessing data within the network and negatively affecting users' ability to use it. However, with the increase in endpoints and migration of services to the public cloud, network security has become increasingly challenging.

Internet security:

This strategy focuses on protecting information that is sent and received through browsers and network security involving web-based applications. It monitors incoming internet traffic for malware and unwanted traffic and uses firewalls, antimalware, and antispyware to provide protection.

Endpoint security:

This strategy provides protection at the device level, securing devices such as mobile phones, tablets, laptops, and desktop computers. Endpoint security prevents devices from accessing malicious networks that may threaten an organisation. Advanced malware protection and device management software are examples of endpoint security.

Cloud security:

With more applications, data, and identities moving to the cloud, cloud security helps secure the usage of SaaS applications and the public cloud. Cloud-access security broker (CASB), secure internet gateway (SIG), and cloud-based unified threat management (UTM) are some examples of cloud security.

Application security:

This strategy involves evaluating the code of an application and identifying vulnerabilities that may exist within the software. Applications are specifically coded to be as secure as possible to ensure they are not vulnerable to attacks.
