Internet security is the branch of computer security related to the internet. It is the process which defines the rules and regulations to protect against internet attacks. It also involves browser security.
We all know that the internet is a great method for us to find and share information online, but it is also an insecure channel for transmission of information. This leads to a high risk of malicious activities such as identity theft, phishing, etc. Most of our lives are dependent on the internet so much, but due to inadequate security, our online identity can be compromised. Any unauthorized person can hack into our accounts and do malicious changes.
With internet security, the transactions and processes done through the internet can be secured. Internet security depends on various standards for securing the data sent through the internet. It is becoming a top priority for most of the companies and the government. If internet security is appropriate, then it ensures the security of all the transactions made over the internet.
A common example of internet security is an online system which prevents credit card numbers from getting stolen on a shopping website.
Threats to internet security
There are various threats to internet security. These include malware (malicious software), botnet, computer viruses, computer worms, ransomware, scareware, spyware, Trojan horse, denial-of-service attacks, phishing, etc.
Internet security tips
The various tips to ensure internet security i.e., to protect the transfer of data are:
Use an anti-virus
Keep your device healthy by avoiding viruses. This can be done with the help of an anti-virus. Anti-virus software can protect the device by detecting and eliminating viruses. You can buy anti-virus software online or from a computer store which gives you protection for one year. You can also download trial versions of anti-virus which gives you protection for about one month. Never use more than one anti-virus at a time on your device.
A firewall protects the information transferred over the network by controlling access between networks. They also check network traffic and block dangerous traffic over the network.
Using security suites can be of great help for ensuring internet security as they contain a suite of anti-virus, anti-spyware, firewall, etc. They also provide theft protection, portable storage device safety check, private internet browsing, cloud anti-spam, etc.
Use password managers
If you are one of those who keeps and manages several online accounts then you need a password manager. A password manager is a software application which helps you to store and organize passwords. You can store the password of each and every account on it. This way you don’t have to remember all the passwords. Just remember the master password which is the key to your password manager.
Beware while sharing your personal information
The information you share online could be used fraudulently by attackers. Be very careful when you are sharing your personal information, especially while you are using social networking websites.
Ensure that the websites are secure
Whenever you are visiting an unknown website which requires you to enter your personal details, make sure that the site is secure. You can do this by checking the presence of a small padlock symbol in the address bar. Also, see that the web address is beginning with ‘https://’ instead of ‘http://’ (the ‘s’ stands for ‘secure’).
Use a VPN connection
Always use a VPN connection whether you’re working on a corporate network or a public Wi-Fi network.
Use layered security
Run an appropriate anti-malware alongside your traditional anti-virus solution. This practice creates layered security which is very important for full protection.
Update your operating system and applications
Regularly update your device’s operating system and software applications in your devices to avoid virus attacks through old patches. Attackers always target vulnerabilities found in outdated applications.
Beware while installing mobile apps
Whenever you are installing new apps on your smartphone, always check if the app is safe. Most of the apps ask for various permissions when you install them. See what permissions the app is requesting. For example, a weather app demanding access to your photos is really not justified!
There are thousands of websites which allow you to download different forms of content. Out of these thousands of websites, several are malicious ones which offer malicious content and steal your personal information. So, always check the website carefully before downloading.
Check your privacy settings
Verify your privacy settings on your mobile and social media accounts. Make sure that you are not sharing private information which could be used against you.
There is no single solution to internet security in this changing landscape of the IT industry. Therefore, focus on your requirements to be as safe as possible always, to protect your digital privacy. The online world could be a great place for you to explore if you take appropriate precautions.
