When in the free network, we want to make the maximum use of it. We want to download information about usage. So the best idea is to deactivate your phone and use the open wifi so that there is no harm to your precious information.

SSL is a security protocol which is used for encrypting the data you are accessing. Google Chrome easily recognizes the site which you visit uses an encrypted HTTPS connection or an unencrypted HTTPS connection with the warning rag "not secure". Read that warning carefully in the address bar of your device particularly while using public wifi. HTTPS ensures that information exchange from the website is secure. A secure SSL connection is needed to encrypt and decrypt the request and the responses. HTTPS network makes online transactions secure and possible. HTTPS encryption is needed to frame the new protocols to establish the network faster.  

 

 

10. Man-in-the-middle

The other Wi-Fi security threat is a man-in-the-middle (MiM or MitM). The hackers divert the data through eavesdropping. The parties are in myth if they are in direct communication with each other while the truth is the attacker transfer messages between two parties and the whole communication is controlled by him. The information obtained by attackers can be used for identity theft, money transaction or password change. The things susceptible to MITM attacks are the sites that require your login information like banking apps, money transaction apps and social networking accounts.

 

 

11. Endpoint attacks

Endpoints like nodes or any device when connected to Local Area Network (LAN) or Wireless Area Network (WAN) and are responsible for two-way communication between the networks. These endpoint threats comprise both malware and non-malware attacks and cause financial loss and steal data. Endpoint security differs from network security, firewall and antivirus. Examples of endpoints are Workstations, Tablets, Laptops, Desktops and Servers. Endpoints are vulnerable access points for cybercriminals. These criminals encrypt the assets and access high-value information. The endpoint security prevents malware attacks, protect the software without affecting the system performance. 

 

 

12. Use two-factor authentication (2FA)

Two-factor authentication requires a password and an authentication code to login into the website. Even if the hackers know your password, they can never guess your secondary code. The secondary security should be changed regularly. When you logged into any website, a code is sent to your mobile number through SMS or voice call or email id. Every time you log in, a different verification code is sent to your mobile number every time. Only after entering the two-factor authentication code, you can log in into the website. 

 

 

13. Use VPN
