Network Security

928e94435e90d05ba4bb87f4bf7bcc22Modern businesses rely heavily on their networks and the conveniences they provide; the speed, interconnectivity, and efficiency that a robust intranet offers a company are invaluable to its daily processes. A company’s network will likely store online correspondence, internal documentation, and even sensitive client information, all available at a few keystrokes to any person with the right credentials. Ensuring the security of this network is of great importance, due to the damaging effects the data can cause in the wrong hands. Yet many small businesses think that their network is beneath a hacker’s notice, and therefore their insufficient security measures will be enough to protect them. All the valuable information found on a small business’s network, paired with the relative lack of security against intrusions, make it an attractive target for various types of bad actors who are intent on abusing that information for their own gain. These creative and determined individuals have shown us repeatedly that a strong firewall and the most current virus-blocking software are not necessarily enough security to protect your network from hackers and scammers. For this reason, MCSI offers network security services to companies in need of a stern defense against cyber threats.

The bad actors that want access to your network will use a variety of methods to try and get their hands on it. While not all cyber threats will involve the use of malware — harmful programs remotely installed on a target computer — all methods will involve some level of deception to get around existing network security efforts. Although cyber criminals’ playbook of scams is ever-growing, certain strategies are commonly used against unsuspecting victims. Your business’s network can be safer if all employees are aware and cautious of these regularly used methods:

Common Methods of Attack
  • Phishing:
    • A bad actor posing as a trusted third party, trying to trick the victim into giving up sensitive information (like account numbers, passwords, social security numbers, etc.)
    • A type of spoofing — uses similar deceitful tactic, but convinces the victim to willingly act against their own interests (download a file or program from a seemingly reputable source that carries a virus)
  • Password Attacks:
    • A hacker uses a program to guess the victim’s password (does not require them to install any malware on your computer or do anything to your network)
    • Can be accomplished through multiple processes (like guessing every possible password, guessing against a dictionary as a reference point, etc.)
  • Man-in-the-Middle Attacks:
    • A scammer exploits a non-secure network connection to interfere in the victim’s online correspondence
    • The bad actor receives all messages and can use them to impersonate each party to the other to discover sensitive information
  • Inside Attacks:
    • Sometimes, the cyber threat who threatens a company’s data security is someone who already has access to the network
    • Disgruntled former employees are the most common perpetrators of this cyber-crime, as they have the passwords and authorizations to get around network security

 The GUARDBOX project is a network firewall distribution, based on CentOS 7 operating system with a custom kernel and including third party free software packages for additional functionality. The software, with the help of the package system, is able to provide the same functionality or more of common commercial firewalls, without any of the artificial limitations. It has successfully replaced every big name commercial firewall you can imagine in numerous installations around the world, including Check Point, Cisco PIX, Cisco ASA, Juniper, Sonicwall, Netgear, Watchguard, Astaro, and more. GUARDBOX includes a web interface for the configuration of all included components. There is no need for any Linux knowledge, no need to use the command line for anything, and no need to ever manually edit any rule sets. Users familiar with commercial firewalls catch on to the web interface quickly, though there can be a learning curve for users not familiar with commercial-grade firewalls.
