Security and IT teams are an organisation’s frontline defenders, tasked with keeping organisations safe from a variety of cyber threats. But their biggest challenge? Spotting and fixing any infrastructure vulnerabilities in the digital systems before they cause any kind of trouble.
When you start digging deeper into digital infrastructure, you’ll realise that vulnerabilities are often lurking in dark corners, waiting to be exploited. Similarly to cracks in the foundation of a building, these weaknesses can seriously compromise the integrity of your infrastructure if not remedied properly.
From outdated software to misconfigured settings, each vulnerability is like an open door for intruders looking to break through your defences. Therefore, these are the top 5 infrastructure quirks that security teams need to be aware of.
The Silent Assassin: Unpatched Software and Operating Systems
Your software and operating systems are like a patchwork quilt as each hole represents a potential security flaw each patch representing a fix. When those patches are not applied, you are inviting all sorts of unwanted guests in. Patches are often released to, as the name suggests, patch a security issue within the target software or OS. The bad news is, hackers are smart, and that patch points them directly at a known vulnerability, this often leads to exploit code being developed shortly after patches are released.
Organisations need to apply these patches before the exploit code finds itself in the wild. While patches are commonly released without patch notes to obfuscate vulnerabilities to less advanced attackers, the fact a patch exists means a vulnerability exists, which means someone somewhere will try to figure it out. It is just what hackers do.
The solution? Keep those patches regular and plug those security holes.
The Gatekeepers of The Digital World: Weak Authentication and Authorisation Mechanisms
Authentication and authorisation mechanisms serve as gatekeepers to your digital citadels, tasked with distinguishing friends from foes and granting access only to the worthy. But if your passwords are weak and controls are loose, it is like leaving the gate wide open for anyone to stroll in with the least resistance. Adding some extra layers of security with multi-factor authentication, strong password policies and utilising the principle of least privilege, you can help keep your infrastructure locked tight against intruders.
Securing The Digital Maze: Misconfigured Network Devices
Misconfigured network devices are akin to installing a highly secure vault door on your safe and not changing the manufacturer pin, it will look secure to the casual observer, but to someone who knows what they are doing, you may as well have installed an open gate. When network devices such as routers, switches, or firewalls are improperly configured, they create openings for malicious actors to exploit, potentially leading to data breaches, network outages, or other security incidents.
These misconfigurations can range from simple oversights such as using default passwords or failing to update firmware, to more complex errors in routing protocols or access control lists. Just as you regularly check that you have locked your windows and doors at night, regularly updating and configuring your network devices will ensure your digital domain is as impenetrable as the Bank of England.
The Neighbourhood Without Fences: Lack of Network Segmentation
Think of your network as a lively neighbourhood, each department or function is a different house. A lack of network segregation is like the housebuilder forgetting to build walls and fences, meaning your data could wander around for everyone to see. To keep things private, you have to set up virtual fences and keep your data neighbourhood in check. This is where network segmentation comes in, by dividing your neighbourhood into smaller blocks – HR, Legal, Accounting, IT – each with its clear boundary, a network compromise will be limited to one specific area of your business.
Broadcasting Secrets in a Crowded Room: Use of Clear Text Protocols
Sending sensitive data over clear text protocols is like chatting about your deepest darkest secrets in the middle of a coffee shop, at peak times, using a megaphone, and there’s no telling who might be listening. To keep your secrets safe, you need to cloak them with encryption, shielding them prying eyes and nefarious eavesdroppers. The vast majority of clear text protocols have more secure versions with encryption as standard. Yes, they can be a pain to deploy and maintain, but their presence significantly increases the difficulty of identifying sensitive data or information for further attacks.
By staying vigilant and patching software holes, beefing up passwords and setting up a virtual neighbourhood watch program, it becomes a lot tougher for intruders to break into your organisation’s systems and access important data. Hackers are human and humans like to take the easy route. And unless you are being actively targeted, having a good security baseline will be enough to redirect malicious user attention elsewhere. Why break into the house with spotlights, CCTV and gates when the house across the road has the front door open?
While there are pre-emptive measures you can put in place, when it comes to safeguarding your infrastructure from cyber threats, thorough testing is key.
