Network security is known to be the act of protecting files and directories within a network. Thus the importance of Network Security is greatly known for most networkers.
In the network, there are still multiple threats that are not controllable and kept on growing, this highly affects the network users’ experience. These are the 6 Growing Threats on Network Security:
1. Destroy systems with Network-based Ransomware
First of all, ransomware is a form of malware that threatens the owner of a certain file with money after encrypting it into a hardly crackable file. The most recent Ransomware that shocks the global networks is WannaCry ransomware, which demands $300 towards over 200,000 victims in a period of 4 days.
2. DDoS attacks are increasing
Second of all, DDoS is also known as Distributed Denial-of-Service, it sends huge waves of unwanted traffics to specific websites and networks. Then, this cripples the server and website forcing it to become dysfunctional and then shut down. Unfortunately, the increase of “DDoS for Hire” and the increasing of IoT devices with low security is what encourage hackers to perform these malicious activities.
3. Insider threat within a company
Moreover, do you know that insiders are the culprit for 25%-75% of the enterprise data breach? Threats from the outside are usually trackable in some ways, but if the threats are coming from internal, it’s a major issue for an enterprise. This is because the acts are hardly detectable. Usually, dissatisfaction of employees or bribery are the main factors causing the actions.
4. Encryption purpose misused
Important to know is that, encryption purpose is to provide a more secure network. In fact, the network perpetrators are able to figure out a way to use it to hide their malicious actions and prolong the time needed for detection of their acts. As time is vital because, in a short amount of time, the perpetrators could perform tons of activities.
5. Cyberattacks using Social Engineering
Furthermore, a few personal information like an email with some extra information could cause your confidential information to leak into the perpetrators’ hands. To show you how it is done, this youtube link will demonstrate you a scenario.
6. Malware disguised as Legitimate
Last but not least, with the usage of off-premises cloud-hosted storage and services, the hacker could register an account to do malicious activities. These activities may include encrypting their malware and able to eliminate the evidence simply by removing the account. Not to mention, vulnerabilities also present in cloud services like Google, Dropbox as the security manager is difficult to block.
