Modern Day Attacks Against Firewalls and Vpns - 2434 Words

Modern Day Attacks Against Firewalls and Virtual Private Networks Electronic technology is growing at a rapid rate; more devices are made mobile and wireless, but with those improvement and developments come flaws and malicious opportunities. Cyber attacks are on the rise and no system or device is immune. Many organizations employ multiple layers of firewalls but that doesn’t completely eliminate the threat. Attacks against firewalls and virtual private networks or VPNs are constantly being exploited with new methods everyday, but they are yet another obstacle that a cyber criminal must overcome. First let’s discuss what a firewall is and what a firewall is capable of doing. Firewall applications are†¦show more content†¦Unfortunately, many firewalls come with so many rules or policies that they can counteract the security desired and create loopholes for network threats or actually block traffic that is desired or requested by the user. These issues make it really important to understand how all rules and policies in the fi rewall work and how to apply them. Another tool often used for secure reasons and also as a reliable method to share information remotely is called a Virtual Private Network or VPN. Henry describes A VPN as â€Å"a group of computers (or discrete networks) networked together over a public network—namely, the internet† (para 3, 2012). Basically, it’s a private network created to allow remote access through a public network. Most often you will see that employees on airplanes or in a public place that will require and utilize these VPNs to access their business resources for all kinds of information, but some people just use it as a means to use their network without physically compromising the actual systems. A good VPN can provide many functions such as access anywhere worldwide without dedicated lines, data security, remote access to business resources and better employee production. For these VPNs to perform these functions properly they are required to provid e reliability by ensuring that the network does not break down before reaching its max capacity, scalability to ensure the ability to expand as business grows, and ofShow MoreRelatedDefining Firewalls And Vpns. What Is A Firewall And How Does It Work?1875 Words   |  8 Pages Defining Firewalls and VPNs What is a firewall and how does it work? Many internet users are concerned about internet safety. A way to combat potential security breaches is to use a firewall. A firewall can be a hardware device or a program and it is used to filter any information that comes through any internet connection to your private network or computer system. Harmful information can be flagged by the firewall program and not be allowed to continue through. Firewalls use up to three differentRead MoreNetwork Security : A Security Platform For Users, Programs, And Computer Networks1667 Words   |  7 Pagesauthentication and authorization to access of data which is controlled by the network administrator.

In modern day operating systems, viruses feed off worm-like infections throughout the systems through attacks and system file modification allowing back-door access. Some of the most common ones include â€Å"trojan horse†. This allows the infected computer to be monitored and controlled remotely. To help prevent / combat these threats, antivirus programs have been developed which help identify some of the most common infection systems and help guard the system against them.

Ultimately, online businesses should prioritize the regular maintenance of their servers and hardware just as much, if not more than, traditional businesses because in essence the assets and day to day operations are performed solely through the servers and technologies that are given that task.

MIMO utilizes a multipath signal propagation that is present in all of today modern communications. The transmitter and receiver already have more than one antenna and use the processing power at either end of the link.
