Firewalls: a crucial security component
Whether on-premise, private cloud or public cloud, firewalls are a crucial aspect in protection of systems. We operate firewalls securely and advise you on necessary activation.
Set-up and operation of firewall systems, remote maintenance, advanced persistent threats
Every company needs a firewall – it protects against undesirable access to the company network and separates specific systems into special protection zones (DMZs). Firewall systems are increasingly complex, so it makes sense to entrust the Pallas specialists with the set-up and operation.
Pallas offers clients professional operation of firewall systems as a Managed Security Service. Today’s modern firewall has multiple components and functions, such as IDS/IPS, UTM, next-generation. We use products from a range of market leaders, including Check Point, Palo Alto, Sophos, Genua and SonicWALL.
Clients with hosted systems protected by the central Pallas firewall are also automatically protected by an IDS. This examines network traffic for critical patterns and anomalies that indicate harmful or undesirable activity. It detects issues such as portscans from outside or bot activities from inside. The detection pattern is updated regularly.
The IDS detects and reports threats, and the IPS reacts and blocks them if necessary. Depending on client requirements, the IPS is usually activated, but can be configured to prevent disruption of operations.
The classic task of the firewall is to monitor ports and addresses, and block them where necessary. Today, the firewall, as the focal point of security for the entire network, has additional tasks, such as IPS, anti-virus protection, VPN gateway, DoS protection (against individual overloading attacks) and authentication. This turns a firewall into a UTM firewall.
The next-generation firewall goes a step further. It examines the application level and blocks unauthorised applications. For example, network traffic to Skype or certain social networks can be prevented; this also applies when these applications are used online.
Pallas’ remote IT maintenance service helps with the performance of IT infrastructure maintenance on-site. A VPN tunnel and secured access are established between Pallas and the customer network. Access options include SSH, MS Remote Desktop (RDP), VNC and browsers (for appliances). All data traffic is limited to the required IP addresses and services. The client can then request Pallas support services by phone or email or via ongoing monitoring where necessary. This means the client always has access to Pallas’ professional expertise and can take part in the knowledge transfer itself. Component monitoring and alerts can take place on the client and/or the Pallas on-call service side.
Pallas uses various procedures to collect, compile, evaluate and perform threat detection for extensive logs in real time. Threat detection through to security incident alerts is the task of security information and event management (SIEM). Long-term anomaly analysis is required for modern, highly targeted attacks known as advanced persistent threats, which penetrate and advance through systems unnoticed, often at a very slow pace.
