Technology Security Threats
With evolution of technology and constant internet connectivity, security threats to technology have also evolved at the same pace.
Types of Threats
Below are the various types of security threats
The most common terminology in the world of security threats is Computer virus. Computer virus is a type of program written to play with the way a normal computer operates without user’s permissions or knowledge. In other words, accessing someone’s machine without permission and making a damage to computer. Virus can enter in computer in different ways like free software’s, downloads, spam emails from unknown senders etc.
Spyware is another critical security threat which can damage a user’s computer by monitoring their online activities and installing a program to their machine without their consent to capture personal information. The most common source of spyware can be softwares/Applications being downloaded over the internet which takes consent from a user with large number of lines in Terms and Conditions which a user usually ignores.
Hackers and Predators
Unlike Computer threats, these are people who can be a threat to information security over the internet. The people who are always looking for victims for their profit by breaking into their systems to steal personal information and use it for their personal gain are Hackers or Predators. The most common activities which Hackers target are Credit card information, steal identity to use for personal gain.
Phishing is a process of stealing sensitive financial and personal information through spam emails or messages. Phishing has been evolving, only the ways to do has changed with time from a fraudulent call in the past to text messages, to emails, to social networking connections.
Mobile malware is one of the latest security threats to technology. Number of users for mobile devices has increased drastically in the recent past and making it more vulnerable way of injecting virus, spyware into User’s device for personal gain and damage.
Social Media Attacks
The latest threat to information and data are social media attacks. Increase of users on social networks have given a new way to hackers and predators to monitor user’s activities for their personal gain. Now cyber criminals are targeting social media to distribute complex geographical attack.
Social engineering is one of the latest development in the evolution of the security threats in the recent past. Social engineering is use of deception to manipulate individuals into sharing their personal information for their personal gain and frauds.
Ways to achieve Technology Security
There are different ways to handle each of threats which are explained above.
Protection against Spam
There are different technologies which can be used to safeguard a system or user’s account from Spam Activities. Below are few techniques defined to save against Spam.
Whitelisting: The technique to filter people who can email a user, all other people are blocked. This is one of the popular techniques in email world to block all unwanted users communicating with users through email. This technique has disadvantages as any genuine unknown user who is not on whitelist is blocked too and it can lead to potential loss to business if a user is not allowed to communicate.
Blacklisting: This is opposite of Whitelisting, technique to filter people who cannot email a user. Instead of maintaining a list of users who can contact, a user needs to maintain the list of users who are not allowed to contact and block them. Maintaining a blacklist is a bigger challenge, as unsolicited users can maintain more number of ways to spam a user’s account and it is difficult to block creating of new accounts. 3
Heuristic filters: The technique to recognize features which are uncommon in normal emails but are frequent in spam to distinguish spam from a normal email.
Machine learning based filters: The technique which uses machine learning algorithms to filter the spams. Using machine’s capability to remember historical activity from each account and deciding on that basis whether to allow a user or not.
DNSBL’s: Maintain database to record IP addresses of spam sources and allow the mail agent to go through the maintained database before a unsolicited user can contact over the internet.
Rate Limiting: allows the user to make a certain amount of calls per day. When the user exceeds the limit, he is likely to be a spam source and will be blocked. This simple technique doesn’t bother average users, but will limit spammers.
Protection against Malware
Anti-Malware softwares can help protection against the Malware attacks by identifying, blocking and removing the malware. Anti-virus softwares, anti-spyware softwares, IP blacklisting, Data loss prevention tools can be few techniques tools which can be used for protection against Malware.
