Network security is the process of taking physical and software preventative measures to protect the underlying networking infrastructure from unauthorised access, misuse, malfunction, modification, destruction, or improper disclosure, thereby creating a secure platform for computers, users, and programs to perform their permitted critical functions within a secure environment.
More simply, it secures the network, as well as protecting and overseeing operations being done.
TEST Technologies’ team of specialists offer a large range of Network Security solutions for business and home. We have the latest skills, security intelligence and technology to significantly reduce Network Security risks.
Network Security has 3 key elements:
- Protection: TEST Technologies can expertly configure your systems and networks
- Detection: Our security systems are almost instantly able to identify when the configuration has changed or when some network traffic indicates a problem
- Reaction: After identifying problems quickly, TEST Technologies systems respond to them and return your business to a safe state as rapidly as possible
This, in short, could be termed a defence in depth strategy. If there’s one common theme among security experts, it’s that relying on one single line of defence is dangerous, because any single defensive tool can be defeated by a determined adversary. Your network isn’t a line or a point: it’s a territory, and even if an attacker has invaded part of it, you still have the resources to regroup and expel them, if you’ve organised your defence properly.
These are the kinds of threats TEST Technologies can discuss and address for your business.
- Access control: Block unauthorized users and devices from accessing your network. Users that are permitted network access should only be able to work with the limited set of resources for which they’ve been authorized.
- Anti-malware: Viruses, worms, and trojans by definition attempt to spread across a network and can lurk dormant on infected machines for days or weeks. Security is aimed at preventing initial infection and also rooting out malware that does make its way onto your network.
- Application security: Insecure applications are often the vectors by which attackers get access to your network. Hardware, software, and security processes lock those apps down.
- Behavioural analytics: Knowing what normal network behaviour looks like, can help business managers spot anomalies or breaches as they happen.
- Data loss prevention: Human beings are inevitably the weakest security link. Security technologies and processes ensure that staffers don’t deliberately or inadvertently send sensitive data outside the network.
- Email security: Phishing is one of the most common ways attackers gain access to a network. Email security tools can block both incoming attacks and outbound messages with sensitive data.
- Firewalls: Perhaps the granddaddy of the network security world, Firewalls follow the rules defined to permit or deny traffic at the border between your network and the internet, establishing a barrier between your trusted zone and the wild west outside. They don’t preclude the need for a defence-in-depth strategy, but they’re still a must-have.
- Intrusion detection and prevention: These systems scan network traffic to identify and block attacks, often by correlating network activity signatures with databases of known attack techniques.
- Mobile device and wireless security: Wireless devices have all the potential security flaws of any other networked gadget, but also can connect to just about any wireless network anywhere, requiring extra scrutiny.
- Network segmentation: Software-defined segmentation puts network traffic into different classifications and makes enforcing security policies easier.
- Security information & event management (SIEM):These products aim to automatically pull together information from a variety of network tools to provide data needed to identify and respond to threats.
- Virtual Private Network (VPN): A tool that authenticates the communication between a device and a secure network, creating a secure, encrypted “tunnel” across the open internet.
- Web security:Providing information and monitoring web use can help to block web-based threats from using browsers which may act as vectors to infect your network.
With escalating threats and a complex technology landscape, it can sometimes be difficult for in-house IT organisations or individuals to keep up with changing requirements.
TEST Technologies’ can support your business to optimise security measures. Our approach to Network Security risk management broadly includes:
- security audits
- penetration testing
- supply and installation of electronic firewalls
- automation of a broad range of IT functions, from basic patch management to vulnerability scanning and data backup
