What Are the Types of IT Security Out There?

IT security is an essential business component to safeguard confidential data.

With most companies using digital tools and networks to carry out their business operations, IT security becomes an essential business component. Many have heard of cyber security, but what is it exactly? Simply put, it is to safeguard confidential data from different types of IT security risks and threats. Below are some of the various types of IT security, such as:

1. Antivirus Software

A software that most computer users are familiar with, an antivirus software is used to protect against malware, including viruses, ransomware, Trojans and spyware. Malware can be dangerous because it can stay dormant for a long period within your network while waiting to attack. Installing an antivirus software can eliminate this threat by scanning for malware entry and further tracking your files to detect any malware that may have slipped and hid itself. For large corporations, they normally subscribe to antivirus softwares that provides a robust, more thorough protection. For students, it is recommended to use lighter antivirus softwares so as to not slow down their laptops or desktop computers.

2. Wireless Security

Wireless security mainly protects a wireless network from unauthorised and malicious access attempts. Usually, wireless security encrypts and secures communication in wireless devices like routers. When there is a security breach, the wireless network administrator will be alerted. The protection is enabled by wireless intrusion detection and IT security prevention systems. Even if the wireless network security is compromised, the hacker cannot view the content of the traffic or packet in transit. Among the common algorithms and standards for wireless network security are Wired Equivalent Policy (WEP) and Wireless Protected Access (WPA).

3. Network Access Control (NAC)

With network access control, you can choose who can and cannot access your network. This is done by identifying which devices and users are allowed into your network. From there, you can set specific security policies like blocking certain devices and controlling user activity within your network. You can also utilise IT security services such as behavioural analytic tools to identify what normal and abnormal behaviour is. Afterwards, you can set it up to receive notifications to detect any suspicious activities.

Alternatively, you can implement firewalls to put a barrier between your private network and public networks to block any threats or dangerous websites.

4. Email Security

Email gateways can be open for a security breach as you send and receive emails. IT security technologies like email security are important for businesses to safeguard personal information that can be susceptible to blackmail and email impersonation scams. Imagine your client receiving an email that is supposedly by you, only to realise the email directs them to a malicious website. With an email security application, it can block these attacks and control email deliveries. 

5. Application Security

Whether it is an application for phones or desktop computers, it can have holes that hackers can access to steal user data. Enforcing application security for major applications such as mobile banking and e-wallet apps will prevent external risks and threats from accessing customer data.
