Why do I need Cybersecurity in place? What happens if I don’t have any?

What happens if I have no Cybersecurity in place?

Having no Cybersecurity in place is like leaving the door to your house wide open when you go out! Look at these common Cybersecurity terms, I’m sure that you are familiar with most:

  • Virus
  • Worm
  • Trojan
  • DDOS
  • Malware
  • Ransomware
  • Phishing
  • Spoofing
  • Credential Harvesting
  • Black Hat
  • Breaches
  • Brute Force
  • Botnet
  • Zero-day Attack
  • Dark Web

These are all Cybersecurity threats and buzzwords that you will hear when dealing with information technology but what do know they all mean?

These are some of the Cybersecurity threats and buzzwords for people, applications and malicious activities utilised by individuals or organised cyber-criminal organisations that are designed to cause damage to your IT infrastructure or reputation, steal personal or corporate information and/or extort money.

In the vast majority of cases, these cybersecurity attacks are completely random, looking for those businesses that have next to nothing or zero cybersecurity measures in place. Although opportunistic, in some cases, these attacks can be targeted against you or your organisation.

How do they get in?

There are various ways this is achieved. In an ever-increasing world of inter-connectivity, we have any number of ways to connect to the internet.  Most of our everyday devices have some form of internet connectivity.  The Internet of Things (IOT), Remote Desktop (RDP), VPN (Virtual Private Network) connections, cloud computing, WIFI, wireless, Bluetooth 3,4 and 5G.  Each of these is a way into your network infrastructure, both at home and in the office.

One of the most common attacks is a phishing attempt. This is where a user receives an email that has a link to a document or webpage that, if clicked on, will install malicious software including viruses, malware, ransomware, and bots, or will redirect the user to a legitimate-looking website where you enter credentials for your bank, email account, and social media accounts. Sadly, the website that you have been redirected to, is fake and is in place to steal from you in some way.

“But I Have antivirus on my computer!”

“Well I have anti-virus installed on my PC, that’s enough”, you say?  Whilst having a good, solid, up to date Antivirus in place is a great step in the right direction, anti-virus does as its name suggests,  it protects you against viruses, unfortunately, It won’t stop any of the other categories of cybercrime listed above.

Let’s give you an extreme example. Imagine you want to meet the Queen. You don’t simply knock on the door to Buckingham Palace and say hello! There are various checks you need to get through to get an audience with the Queen. Background checks, ID checks, physical checks, fencing, barriers, security, armed guards, etc.

IT and cybersecurity should be the same and use a layered approach (sometimes referred to as the security onion – remember Shrek?) with hardware and software designed to mitigate the risk to all of the attack vectors currently being employed by malicious actors. In other words, keep the bad guys out) Each one of the controls listed below acts as a deterrent and combined makes it harder for the actor (baddie) to gain the information being sought. These controls will include (but are not limited to) some or all of the following:

Physical security

  • Fencing
  • CCTV
  • Mantraps
  • Guards
  • Biometric readers
  • Alarms and/or motion detectors
  • Proximity card readers
  • Warning Signs
  • Locked server rooms and/or cabinets

Network security

  • Hardware Intrusion detection and prevention systems (HIPS/HIDS)
  • Hardware firewalls
  • Access control lists (ACL’s)
  • Virtual Local access networks (VLAN’s)

Computer security

  • Host-based firewalls
  • Anti-virus and anti-malware (endpoint protection)
  • Security updates and patching
  • Application updates and patching
  • Anti-spam applications
  • Application control and whitelisting
  • System restore points

User security

  • User credentials and biometrics
  • Multi-factor authentication
  • Security training and awareness
  • Policies and procedures

Cost is usually a major factor in the decision making when it comes to implementing security measures. Even with the most robust IT and cybersecurity measures in place, this cannot make your organisation 100% secure as it’s only as good as your weakest link.

(Often, it’s an employee who accidently “clicks” on a rogue email link by mistake. We have FREE cybersecurity training in place to help with this here).

By layering the security and employing multiple IT and cybersecurity controls, equipment and training staff to recognise potential scams, it can minimise the risk to your data, reputation or even your livelihood.
