Cyber criminals are rapidly evolving and trying to breach our systems with enhanced and advanced attacking strategies. An attack on the security network could bring high degree of failure in the security system, but the implications of an attack on the corporate network can be far more troubling. The devastating impacts of corporate network breach could lead to denial of service and corporate data theft that is unbearable for any organization.
Of course we cannot limit a hacker’s expertise, but a strong network security design will require the hacker to have a greater amount of expertise. For that we must look ahead to identify some of the potential threats in corporate network. Here are some ways your network can be attacked:
USB drives are one of the most common ways to infect a network from inside a firewall. As USB’s are inexpensive, small, hold a lot of data and can be used between multiple computer types, it’s the golden master key for attackers. The ubiquity of thumb drives has driven hackers to develop targeted malware, such as the notorious Conficker worm, that can automatically execute upon connecting with a live USB port. Moreover, many operating systems have default configurations that enable most programs (including malicious ones) to run automatically.
Many employees use corporate laptops and notebooks for their routine task. However, these devices are also being used outside the organization for personal use. It makes it vulnerable, as the user may download malicious files or get infected through malicious link. These devices work as a gateway to the organization’s network and information. These devices may contain some forms of sensitive information that absolutely cannot leave the walls of the building (salary information, medical records, home addresses, phone numbers and Social Security numbers are just a few obvious examples), that can harm organization of lost or stolen by attacker.
Wireless Access Point:
Wireless APs provide immediate connectivity to any user within proximity of the network and are naturally insecure, regardless if encryption is used or not. Wireless attacks by wardrivers (people in vehicles searching for unsecured Wi-Fi networks) are common and have caused significant damage in the past. Moreover, protocols such as wireless encryption protocol contain known vulnerabilities that are easily compromised with attack frameworks, such as Aircrack. More robust protocols such as wireless protected access (WPA) and WPA2 are still prone to dictionary attacks if strong keys are not used.
E-mails are frequently used within businesses to send and receive data; however, it's often misused. Messages with confidential information can easily be forwarded to any external target. In addition, the e-mails themselves can carry nasty viruses. To prevent harm from email scams and attacks, enforce security policy and bound employee to avoid sending critical information over email outside the organization.
However, these are some of the common techniques that can benefit the attacker if not taken seriously in an organization. The attackers have eyes on us and waiting for a single mistake to take benefit from. Enforce high end security policies and restrict information access and network access to prevent any breach to corporate network and information.
