In cybersecurity, filtering and monitoring are proactive measures that act as your digital watchdogs, guarding against threats by controlling what comes in and out of your networks and systems, and by continuously observing activity for suspicious signs. These practices are essential for early threat detection and prevention.
Printers are often overlooked, however, they can represent significant security vulnerabilities if not properly secured. Modern printers are essentially specialised computers with network connections, storage capabilities, and their own operating systems, making them potential targets for cybercriminals.
In any organisation, and even for individuals with multiple devices, simply knowing what hardware and software you own is the foundational step for effective cybersecurity. This practice is known as asset management, and it's far more than just an inventory list; it's a critical component of risk management and security posture. You cannot protect what you do not know you have, or what state it's in.
When upgrading your tech or getting rid of old devices, simply deleting files or formatting a hard drive is often not enough to truly erase your data. Safe disposal of hardware is a critical, yet frequently overlooked, aspect of cybersecurity. If sensitive personal or organisational information remains recoverable on old devices, it can easily fall into the wrong hands, leading to identity theft, financial fraud, or severe data breaches.
Anti-virus and anti-malware are essential tools that are designed to detect, prevent, and remove malicious software – collectively known as malware – that can infect your devices, compromise your data, and disrupt your operations. Just like your body needs an immune system to fight off infections, your digital devices need protection against cyber threats.
In the fast-evolving world of cybersecurity, software, operating systems, and applications are constantly being refined, improved, and, crucially, secured. Regular updates, also known as patching, are not merely about gaining new features or improving performance; they are an absolutely critical cybersecurity practice. Neglecting updates is like leaving your digital doors wide open after a burglar has already identified the weak spots.
In cybersecurity, access control for users is about ensuring that only authorised individuals can access specific systems, applications, and data, and only to the extent necessary for their role. This principle is often referred to as the "principle of least privilege" – granting users the bare minimum permissions required to perform their job functions, and nothing more.
Your Wi-Fi network and broader internal networks are the digital gateways to all your connected devices, resources and data. Just as a physical building needs secure entrances, your networks require robust access controls to prevent unauthorised entry and protect everything within. Ignoring network security is like leaving your front door wide open.
The shift to remote work has transformed how we work, but also introduces new cyber security challenges, particarly around access control in a less structured environment, like a home office. When working off site, your personal network and devices become potential entry points into your organisation's systems, making robust access control crucial.
Multi factor authentication is considered the most impactful single step you can take to strengthen your access control to digital accounts, systems and data. While a strong password is your first line of defence, MFA adds a critical second (or more) layer of verification, making it much harder for cyber criminals to gain unauthorised entry, even if they've stolen your password.
Cyber security awareness isn't static; it evolves with new threats and changes in technology.
Technology alone will not fully protect an organisation; people are often considered the weakest link or biggest vulnerability in the security chain, but they can also be the strongest. Cyber security training is not just an option, but an absolute necessity.
