Here is a list of some of the security issues that browsers present.

1. Browser History: The browser history is a mechanism to track the internet behaviour of users. This includes knowing what the user does on a site and which sites they visit. By getting accessing to these history files, the criminals can know which sites their target has been using. This knowledge on their part can also lead to phishing attacks against users and obtain the credentials, establishing purchase habits, payment history etc. There can also be cases of blackmail if the websites the user visited prove to be unethical or illegal.

Solution– Clearing the browser cache is a first step towards minimizing the cracks through which a cyber attacker can enter. In particular, knowledge of financial information such as online banking can make the user extremely vulnerable. Browser history can be cleared manually or adjust the setting to do so automatically when closing the browser. Incognito or Private mode can be used if you do not wish to save anything you are doing on the internet.

2. Saved login credentials: Saved logins and bookmarked pages for the sites visited are a combination that opens up newer possibilities for hackers. While some sites require two-factor authentication for logging in, many of them utilize it only as a one-time login verification method. Subsequent access to the website might go unchallenged and this is where the problem lies. With emails, an attacker can get into the personal information of the user, if he can access the saved credentials. If they can get the email address and a password, they can work their way into every information that a user may have classified as private.

Solution– Login credentials should not be saved in the browser. Rather, free password managers can be used to store passwords.

3. Autofill information: Autofill information can be dangerous too. Browsers can save you address and contact information, but what would happen if the device is hacked or stolen? An attacker will know where the user lives, what their address and phone number is, and other details that can give them away.

Solution– Autofill should be turned off especially when entering any confidential or personal details.

4. Cookies: Cookies are files stored locally which can identify users and link them to sites. They are a major potential threat to any user. Cookies can divulge personal details about the user and help an attacker plan his next move. As mentioned previously, incognito or private mode will come in handy here too.

Solution– Disabling cookies is a possible solution, but sometimes many sites limit their functionality if cookies are turned off. Cleaning cookie data periodically can help, though that might mean entering data on websites again after being prompted several times.

5. Browser Cache: The browser cache involves storing portions of web pages for easier loading on subsequent visits, which can hint at which sites you have been on and what you have seen. Malware can be adjusted to take advantage of cache data as well.

Solution– Manually clearing the cache data is helpful, especially after sensitive information has been provided or accessed on website pages. Incognito mode is helpful in this scenario as well.

6. Redirects and pop-up ads: Pop-ups are not just annoying; they can also be malicious. They compel users to visit unsafe pages or download malware. Promising exciting gifts, lucrative offers and making it impossible for the window to be closed, they are an effective way for attackers to redirect the user. These kinds of threats operate out of their heavy reliance on users reacting impulsively.

Solution: If a user feels that the website has redirected them from the page they were visiting, action should be taken immediately. The system should be scanned for malware and taken offline until action has been completed. Conclusion Internet browsers are quintessential for every individual and business. In fact, what is known as ‘the internet’ is because of these browsers. It is vital to take steps to keep security intact and block any possible loopholes. The first step is recognizing these threats, and then to take action against them is equally necessary.   About SNS Secure Network Solutions (SNS) provides a quantifiable, risk-based approach to building a global structure of cybersecurity infrastructure based on internationally recognized frameworks and practices.
