The computer’s and the Internet are the most extraordinary inventions that took place in the last century. These two together have transformed the lives of the entire mankind.But, there are some people who are called hackers and intruders who indulge in wrong and unauthorized ways to access the data. When users go online, their personal information may be exposed in a number of different ways
To safeguard themselves from these people, Internet security procedures should be understood and practiced.Hence it has become highly important that data security and encryption must be given top priority so that your devices can have a foolproof Internet security.
The most well-known threats to Internet security are computer viruses. A virus is a self-replicating program that can infects a device and makes a number of unwanted changes in the system like making it useless or deleting data from within the hard drive.Spyware is another common type of malicious software. Some spyware tracks and monitors Internet usage for marketing purposes. The most dangerous spyware may include key loggers which records and transmit everything that a user types. Hackers can then use this information to access a user’s accounts and for identity theft and fraud.
Users can protect themselves by using the following Internet security protocols:
Firewall – A firewall can help you keep a network secure by controlling incoming and outgoing traffic by analyzing data and using a predetermined set of rules. It can be hardware or software-based. Often, firewall can be found built directly into the operating system, or you can get an additional firewall from security firm.Additionally, many broadband routers have rudimentary firewall capabilities built in.
Antivirus and antispyware’s – These software scan the system real time and analyze programs and files as they are downloaded on to the user’s system. Users should scan their entire computer system to check for malware that may have slipped through, or that was not yet identified by the software. It is crucial that users keep their software up-to-date as new viruses are frequently developed and identified.
Disable the ability to run scripts without permission – some Web browsers will allow users to block scripting. Because scripting is needed for infected or malicious websites to install code onto a user’s computer, disabling this ability will serve to protect users.
Monitor mobile devices for the presence of unauthorized software additions – Users may occasionally be prompted to update an application on their mobile device that they do not remember installing. This may be a sign that their device has been infected. Users are advised to periodically look through the applications on their devices and delete any that are unimportant or that they do no use.
Third-party cookies – Most Web browsers allows users to block cookies. While most cookies present no threat to the user, a few can. Blocking the cookies can provide a bit of security to a user.
Suspicious emails – Sometimes, hackers send an email that appears to be from a known source by embeding a Viruse’s and Spyware in it. Within the email there will be a link which can infect a user’s computer and present a security risk on clicking the link. The link may also be a phishing scheme that will trick users into entering usernames and passwords into a bogus site.
Strong Passwords – Users should use strong passwords that include capital and lower case letters as well as numbers and special symbols. People should not use passwords that are easy to guess, such and names of family members or pets.There should be a different password for different account’s so that if one account is hacked , the hacker can use it to hack your otheruser account.
