Against a growing number of sophisticated cyber security threats, protecting your business is a constant battle.


Security solutions like firewalls and antivirus software have long played an important role in defending against malicious attacks. The evolving nature of threats however, means these traditional technologies are increasingly ineffective at standing up to the latest nefarious actors.

In a hostile digital landscape, the most effective way to defend your organisation’s critical assets from criminals is to adopt a proactive rather than reactive approach to cyber security. This involves routinely seeking out vulnerabilities and hunting for threats before they cause serious damage.


The evolution of cyber threats


Today’s persistent cybercriminals are determined, persistent and well-funded. Attackers will use any and all means to target your business, frequently changing their tools, tactics and procedures (TTPs) to avoid detection.

Rapid workplace digitisation, including the rise of cloud technology and BYOD, has created a growing attack surface that is vulnerable to compromise. This, combined with the widespread availability of black hat tools, means that the number of threats facing your business is rising at an alarming rate.

As well as common malware-based threats such as viruses, worms, trojans and ransomware, your organisation also faces the challenge of protecting itself against bruteforce and distributed denial-of-service attacks (DDoS), plus a range of unscrupulous social engineering techniques including phising, vishing and spear phishing.

The ability of human attackers to think outside of the box to develop new methods of compromise means that threats are growing more and more sophisticated. Advanced Evasion Techniques (AET) where malicious code is divided, obfuscated and delivered over several layers of a network simultaneously, are now common.

The covert and incessant nature of Advanced Persistent Threats (APT) means that attacks can go undetected for long periods.

You can’t rely on perimeter security alone


Preventative security such as firewalls and antivirus software form a crucial part of any organisation’s security armoury, but relying solely on the protection they offer leaves critical assets vulnerable.

These systems are only capable of stopping known threats that have recognised file signatures, meaning they struggle to identify new forms of malware, polymorphic threats and other AETs.


How to achieve a proactive approach


Embracing a proactive approach to cyber security is the only way that your organisation can effectively mitigate the risks posed by threats that bypass your perimeter security. Such an approach also helps reduce the risk of other technological and procedural deficiencies, such as a failure to patch and properly configure internal systems. It can also help to reduce the dangers of human error, such as the opening of malicious email attachments.

To develop a proactive approach to cyber security, your organisation should embrace two key practices. The first is to conduct regular security assessments that test your technology, people and processes against the latest attack techniques.

The second practice is to implement a monitoring and response operation capable of hunting for and responding to threats and breaches across your network and endpoints. This is necessary to achieve the enhanced visibility needed to stop suspicious activity in its infancy and minimise the dwell time of attacks.
