Overview

What is network security?

Network security is a term used to describe practices and policies designed to defend IT networks and data against unauthorised access, misuse, modification and exploitation.

Organisations that fail to implement a strong network security framework leave themselves vulnerable to cyber-attacks. With the financial and reputational damage of breaches higher than ever, network security is now a key boardroom concern.

Threats

With so many threats, comprehensive
security is a must

As your business grows, so does its attack surface. The proliferation of cloud services and remote working are just two examples in a line of current IT trends that can increase exposure to threats.

While traditional preventative security technologies such as firewalls and antivirus are important network security controls, they are not capable of protecting your organisation against all types of attacks.

Common threats to your network security include:

Malware

Malicious code designed to compromise a user’s privacy by stealing and destroying personal data can be introduced via a wide variety of sources, including email attachments, downloads, bogus advertisements and webpages. It's essential to identify and disrupt attacks before they spread.

Ransomware

A form of malware designed to cause widespread disruption by infecting multiple systems on a network, locking down machines and demanding a ransom for their return or decryption.

Password attacks

Brute force is a common method used by cybercriminals to gain access to user accounts. Using a variety of methods, including the use of automated applications that enter thousands of common word and number combinations in sequence, hackers can crack weak accounts in minutes.

Social engineering

By imitating the communications of known individuals and businesses, social engineering scams trick users into clicking infected links or divulging personal information like passwords. Highly personalised spear phishing and Business Email Compromise (BEC) attacks target high privilege users and can be highly damaging.

Denial-of-service attacks

By flooding a network with high volumes of useless requests and data, DoS attacks overload vital services until they no longer function. A distributed DoS attack is conducted by many, often thousands, of sources so if not detected early can be very hard to stop.

Man-in-the-middle attacks

By sitting between the connection of two parties and observing traffic, cybercriminals are able to intercept and manipulate sensitive information such as bank account details. These difficult to detect attacks target key communication channels such as Wi-Fi, meaning that close monitoring is required to identify them.
