Information security and hackers have always been sworn enemies. In most instances, one is always trying to overwhelm the other. Many organizations and businesses have fallen victims to unscrupulous individuals who hack into their systems and access their sensitive data or information. At times, these hackers corrupt the data and render them useless. The ability of hackers to access companies’ networks owes credence to poor network security technologies.
Varieties of network security technologies
There are numerous kinds of network technologies that can forestall the actions of hackers. Such technologies allow businesses, government institutions and public organizations to ward off unauthorized entries into their networks. Examples of these security technologies include:
· Internet protection
Most hackers use the Internet as a gateway to access other people’s networks. Internet-based network security protects the network from such attacks using the firewall. This technology filters the packets that enter or exit the network. This way, hackers are kept at bay while employees cannot access dangerous sites. The firewall can also be translated into a NAT (Network Address Translation). The NAT proxy ensures that the internal IP address remains concealed from others outside the network.
· Intrusion Prevention Systems
Other network security technologies can assist organizations to shield themselves from attacks. These technologies have the capability to unearth any impending attacks. Then, they send alerts while taking pre-determined steps to stem these attacks. Intrusion Prevention Systems or IPSs usually disable the Internet connection or network segments in a bid to halt any unidentified intrusions. They have proven to be invaluable in forestalling network intruders before they wreck havoc to the network.
· Intrusion Detection Systems
Unlike IPSs, Intrusion Detections Systems (IDSs) use anomaly-based and signature oriented detection algorithms to keep an eye on the network traffic. They then notify the network personnel at the slightest detection of any attack. They are passive systems in contrast to IPSs. Nevertheless, they still have the ability to unearth attacks or suspicious activities at the slightest instance.
Certifications involved in network security technology
Business organizations and government institutions ought to enlist the services of experienced IT companies. Such firms have the requisite experience to handle the aforementioned technologies and use them for maximum success. Companies with a reputation for delivering good services possess numerous certifications. Such certifications and accreditation include:
· ISO 27001
This certification is key in enabling companies undertake network security technology tasks successfully. It helps these IT firms to formulate the requirements for the implementation and operation of ISMS (Information Security Management System). ISMS is important in enhancing these firms’ ability to mitigate business threats and risks associated with information technology.
· ISMS certification
ISMS certification is usually the preceding certification before companies gain the ISO 27001 certification. IT firms that are competent in network security technology usually pass through the hands of independent auditors. These auditors must produce an audit report after analyzing the companies’ ISMS. The certification process culminates in a review spearheaded by an independent certification committee.
The ever-changing face of technology has necessitated a metamorphosis of network security technologies. What has not changed is the immense importance of these technologies to network security. The right network security system will be pivotal in keeping all hackers at bay. This would be a body blow to these unscrupulous individuals.
