Is there security on the Internet?

Answer 1

For the typical user the answer is most certainly no but it depends entirely on how you define "sent via the internet." If you connect to a web site using the standard http protocol then it is an unsecured connection. If you are using the https (SSL) connection then it is encrypted and gives some degree of security however there are man in the middle attacks that can defeat SSL connections.

If you are talking about sending email then there is no security as the message crosses the internet unless you encrypt it with something like PGP. You can have TLS encrypted connections between mail servers that will protect the message as it crosses the internet but once it is received by the mail server it is unprotected. Thus the network connection between your client and the mail server is not secure. The message can be sniffed off the network and read.

The same goes for your user name and password for a typical POP3 mail account (most ISP accounts), it can be sniffed off the network and stolen. So bottom line is for the most part information sent via the internet is not secure unless specific measures are taken to secure it.

Answer 2

Protection of data has been an issue ever since the first two computers were connected to each other. With the commercialization of the Internet, security concerns expanded to cover personal privacy, financial transactions, and the threat of cybertheft. In IoT, security is inseparable from safety. Whether accidental or malicious, interference with the controls of a pacemaker.

Security controls have evolved in parallel to network evolution, from the first packet-filtering firewalls in the late 1980s to more sophisticated protocol- and application-aware firewalls, intrusion detection and prevention systems (IDS/IPS), and security incident and event management (SIEM) solutions. These controls attempted to keep malicious activity off of corporate networks and detect them if they did gain access. If malware managed to breach a firewall, antivirus techniques based on signature matching and blacklisting would kick in to identify and remedy the problem.

More recently, concerns over the authenticity of software and the protection of intellectual property gave rise to various software verification and attestation techniques often referred to as trusted or measured boot.

Answer 3

Until your system is protected with anti-virus program your system is secure and protected to some extent as if you are connected to internet you need to be sure to remain secure from online threat and virus.
