Best Firewall Security services in Canada

Firewall configuration matters in security
Firewall testing typically presents the most straightforward and compelling proof of the ‎efficacy of a firewall if done correctly. Understanding that a firewall will survive the same ‎threats that network attackers currently use creates a strong degree of faith in the ‎firewall. Failing to withstand those attacks exposes unique security exposures in the ‎firewall to remedy them.

Another beneficial result of firewall testing is to discover and correct these vulnerabilities ‎before hackers find them.‎

• A correctly configured firewall allows authorized users to access inbound and outbound ‎data and blocks data access by unauthorized users.‎ ‎
• A correctly configured firewall can block the IP depending on certain parameters, which ‎include too many links, failed login requests, port scan, and other malicious activities, ‎which are configured in the firewall.

According to recent research by Gartner, 99% of firewall breaches would be from ‎misconfigurations in the coming years.‎

• ‎Compliance violations
• Broad policy configuration ‎
• ‎Risky rogue services
• ‎Non-standard authentication mechanisms
• ‎Log outputs from security devices

Goal
Such testing aims to determine the security of the whole network concerning the ‎probability of remote access from an external location.‎

Approach
During a firewall test, Invesic's security experts, try to hack into the target firewall ‎device from an external location on the network, which most often is the Internet. The ‎testing techniques used are the attacks performed by actual network intruders. Certain tools like NMAP, TCPDUMP, etc., are very helpful in the process of testing. After the testing report is generated.‎

Retest
The report is then explained to the client and discussed. If they request a retest, we will ‎present them with a few options and the retest will be completed.‎ If necessary, Invesics offers post-retest consulting. The organization's most pressing ‎need is customer satisfaction.‎

Phase 1: Indirect Information gathering i.e. gathering information from outside the network

Phase 2: Direct Information gathering i.e. gathering information from inside the network

Phase 3: Attempts to penetrate the firewall from outside the network

Phase 4: Attempt to penetrate the firewall from inside the network

• ‎Does the firewall properly enforce an organization’s firewall policy?‎
• Do the firewall and other components within a network properly enforce an ‎organization’s network security policy?‎ ‎
• How well do the firewall and other network components protect against ‎externally initiated attacks?
• ‎How effective is the network’s security perimeter? Does leakage, an access route ‎to a network that bypasses the firewall’s defences, exist?‎
• How much information about a network is available from outside a network?‎
• ‎Do the firewall and other machines within the target network generate alarms ‎when attacks are launched?‎ ‎

• Default features will not cover all the areas of attack.‎
• The limits in the settings may not be relevant for getting maximum performance ‎either they are too low or very high values, we need to analyze the server usage ‎and optimize it to get maximum performance.‎
• Alerts are either disabled or enabled all alerts. We need to configure it to send ‎necessary alerts only.‎
• ‎Number of blocking IP’s may be very less to avoid consuming resources by the firewall. ‎But in big shared servers, a high number of blocks needed.‎
