Cyber Security

PROTECTING YOUR USERS, DATA AND BUSINESS FROM MALICIOUS THREATS

Cyber-security risk is the most significant threat to all organisations due to reliance on IT systems, the Internet and wireless access. Due to the exponential increase in the cyber threat landscape and sophistication of attacks, cyber attacks are one of the major challenges in the contemporary world. Lumen IT’s cyber-security solutions aid in the protection of your business and your users by preventing the theft of or damage to hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.

Protecting against Email Fraud through Secure Email Gateways

Email Fraud is the most highly-targeted attack vector in the cyber-security landscape. It uses social engineering to prey upon unsuspecting users merely responding to requests in doing their job. Credentials can be stolen and funds transferred often before a threat is identified.

Secure Email Gateways (SEG) are used to effectively filter out any such malicious emails before they get to the user.

Security Awareness Training

Make users part of your cyber defence by providing the necessary training to identify the risks of cyber-attacks. All organisations should create a culture of security awareness and Security Awareness Training extends to USB sticks, suspicious emails and general security practices in the workplace. Combined with a phishing simulator, organisations can get a baseline of their security profile.

Cloud Access Security Broker (CASB)

Usually cloud-based software that protects other cloud applications such as O365 by monitoring users activity and enforcing security policies. CASB solutions can be used to report, alert, malware prevention, escalating 2FA/MFA enforcement. This technology allows organisations to deploy cloud applications with confidence and reducing the risk of infiltration.

Access Management (PAM)

PAMs are solutions to secure, control, monitor and manage key admin accounts in a secure repository, isolating the, use and reducing risk of them being used in an unauthorised fashion or being stolen. Using a PAM enforces logging of all admin account activity, thus ensuring a high level of compliance and protection of all ICT resources.

Identity, MFA and SSO

Ensuring proof of identity has become a critical element of ICT security. From 2-factor authentication (2FA), the market has moved to multi-factor, ensuring the highest protection from data and ICT assets of all types. Such technologies employ PINs & passwords, but also biometrics, physical checks (GPS location or IP address), access tokens/cards/keys to identify valid users of systems.

Identity Breach Detection and Prevention

The majority of breach attempts look to steal credentials. Hackers use credentials to permeate servers and networks in order to exfiltrate or encrypt data to extort ransoms.

A multi-layered approach to identity protection is therefore needed, to combat the rising threat of identity-based attacks. Identity Threat Defence solutions tackle this issue with preventative controls and active threat detection.

DMARC Email Authentication

When deployed with SPF and DKIM, only DMARC is able to ensure that a receiver is opening an email from an authenticated sender. DMARC is used to protect the reputation of your business so that fraudulent emails appearing to be sent on your behalf (email spoofing) are rejected. DMARC is a standard being adopted by governments and corporations across the western world; and since early 2024, consumer email systems such as Google and Yahoo are mandating it for B2C senders.

EDR (Endpoint Detection and Response) for Servers and Desktops

A multi-layered approach should be employed for virus and malware protection: on the desktop and at the server. EDR tools examine indicators of attack to identify known threats, with sandboxing in the vendors' lab should there be any early indication of an attack. Server Protection extends into cloud-deployments of virtual server infrastructure.

The very best EDR solutions are deployed as a fully managed service with full remediation of identified providing peace of mind for any organisation.

Penetration Testing

Authorised simulated attacks on your ICT infrastructure aid in the validation of the efficacy of your deployed security platforms. Pen Tests will identify known weaknesses, but also confirm the strengths of the platforms and systems in use. They are delivered with a report that provides actionable remediation steps to raise the bar from a security standpoint.

Network Security

With today’s threat landscape, traditional network security is no longer enough to keep your networks safe. You need a proactive, machine learning-driven approach that processes network traffic and applies rules to block potentially dangerous traffic. Next-generation firewalls (NGFWs) embed machine learning to instantly detect and block sophisticated attacks.  They can be implemented in hardware or software and enforce security policies at the application, port and protocol levels. With global threat intelligence and advanced automation incorporating machine learning, NGFWs provide automated intelligent policy recommendations with platforms that are simple to manage.
