As technology continues to advance many people has started to feel concerned about personal security which is on risk which leads to cybercrime and online activity, since the internet was created many have used it for their personal benefits leading to many security breaches that have caused huge financial damage to both individual and corporations. Even now after the best ways were given for securities many dangerous security breaches can still take their tall on corporative activities .
fortunately there are information about the threats so professionals and individual can make their way to secure network. As there was this cyber attacks targeting industrial control system on the rise because of several security breaches so the Top Causes of these Data Breaches are There are many causes for such breaches that all professionals should be aware of.
The vast majority of the concerns come from malware infections, which stand at a frightening 44% of all incidents. 30% of all incidents come from accidents that occur on the inside, usually because of an employee or company system. 27% of incidents are a result of hacking attempts. 26% occur because of SQL injections, while 24% occur because of a compromised password. In 19% of all incidents ,the attack was intentional or targeted at the corporation to achieve a certain end. One of the simplest and easiest ways we can protect our data is to use secure protocols.
Many of the more common and older protocols, such as File Transfer Protocol (FTP) for transferring files, Telnet for interacting with remote machines, Post Office Protocol (POP) for retrieving e-mail, and a host of others, deal with data in an insecure manner. Such protocols often send sensitive information, such as logins and passwords over the network. Network security protocols are one such category that makes sure that the security and integrity of the data are preserved over a network. Various methodologies, techniques, and processes are involved in these protocols to secure the network data from any illegitimate attempt to review or extract the actual content of data.
Some network security protocols
Here are the lists of some popular network security protocols that you must know to implement them as and when required:
1. IPSec protocol is classified by the IETF IPSec Work Group, which offers authentication of data, integrity, as well as privacy between 2 entities. Manual or dynamic association of management in cryptographic keys is done with the help of an IETF-specific key managing protocol named Internet Key Exchange (IKE).
2. SSL, i.e., Secure Sockets Layer, is a standard security mechanism used for preserving a secure internet connection by safeguarding different sensitive data which is being sent and receives between 2 systems; which also helps in averting cybercriminals from reading as well as modifying personal data, packets or details in the network.
3. Secure Shell (SSH) was invented in 1995, a cryptographic network security protocol used to secure data communication over a network. It permits the command-line to login remotely as well as the execution of specific tasks remotely. Various functionalities of FTP are incorporated in SSH. SSH-1 and SSH-2 are the latest of its kind.
4. Hyper Text Transfer Protocol Secure (HTTPS) is a secured protocol used to secure data communication among two or more systems. It set up an encrypted link with the help of Secure Socket Layer (SSL), now known as Transport Layer Security (TLS). Since data transferred using HTTPS is in the encrypted format, it stops cybercriminals from interpretation and alteration of data throughout the transfer from browser to the webserver.
5. Kerberos is another network validation protocol that was intended for providing a strong authentication between client-server applications with the help of secret-key cryptography. According to the Kerberos network validation protocol, all of its services and workplaces correspond to an insecure network, making it more secure and responsible.
As a security professional, it is essential to know these protocols and where they are used. There are scenarios where HTTPS becomes HTTP , or at times where your company page opened without HTTPS or SSL, you can understand that either the link is opened from a spam mail or illicit mail or anyone is trying to perform a phishing attack. Or, someone is trying to compromising the internal network by the downgrading of the HTTP attack.
