Emerging Data Security Technologies

On June 17, 2019

There has been an exponential increase in cyber-attack instances across the globe. This has led to a need for more advanced data protection and cyber security solutions which can defend organization’s IT systems and can protect business and consumer’s data. In such a scenario, newer technologies play a very important role in providing state-of-the-art data security solutions.

Some of the prominent technologies that are giving rise to possibilities of better data security in future are:

Hardware Authentication: It is easier for hackers to get access to information systems due to inadequate passwords and usernames. This compromises sensitive data and urges the experts to come up with strict authentication methods. One of the ways, to accomplish this, is the development of user hardware authentication. Hardware authentication can be particularly essential for Internet of Things where it is important to ensure that any device seeking connectivity has the authorization to do so.
User Behavior Analytics (UBA): It is a cybersecurity process that detects threats, targeted attacks and financial frauds. It gains information about network events like any kind of malicious behavior by attackers, unauthenticated usernames and passwords, etc. UBA is a valuable tool to train employees for adopting better security practices.
Data Loss Prevention: Encryption of data can protect it on field and sub-field levels. Though any business process can be performed on encrypted data in its protected form, the attackers cannot monetize data even if they conduct a successful breach. For data loss prevention to work well, enterprises should ensure compliance to data privacy and security regulations.
Cloud Technology: Transformation of system security technology will be impacted significantly through the cloud. Users have embraced cloud technology to store vast amount of information that is generated on daily basis. Migration from on-premise data storage and development of information systems security to be used in the cloud is emerging gradually.
Deep Learning: Technologies like deep learning consist of artificial intelligence and machine learning. Experts have a significant deal of interest in these technologies for the purpose of system security. They focus on anomalous behavior as whenever AI and machine learning are fed with right data regarding a potential security threat, decisions are made to prevent attacks depending upon immediate environment without human input. Deep learning techniques have made it possible to analyze different entities that are found in an enterprise both at micro and macro level.

Combination of these new technologies and fundamental security controls can help in ensuring that the confidential information of an organization is safe. For more information on emerging data security technologies, call Centex Technologies at (254) 213-4740.

What Is Packet Sniffing?

In Security

Information is often broken into smaller units when it is transmitted over the computer network. These small units known as data packets are fragmented at the sender’s node and are reassembled in their original format at the receiver’s node.

Every data packet has to cross a number of traffic control devices such as routers & switches. However, the data packet is susceptible to the risk of being captured each time it crosses these control devices. This act of collecting data packets illegally by hackers is known as packet sniffing. Hackers often use specialized devices
known as packet sniffers to do so.

How Does A Packet Sniffer Work?
A packet sniffer can exist in the form of software or hardware specifically designed to collect the data being transmitted over the network. They intercept & log network traffic with the help of wired or wireless network interface it has an access to. Hackers might use it to capture:

User names
Passwords
Downloaded files
Emails
Audio & video activity
Other sensitive information

An illegal packet sniffer is installed somewhere on the network without the knowledge of an IT administrator to gain unauthorized access to confidential information. Hackers also use sniffers to eavesdrop on unencrypted data to spy and checkout information being exchanged between the two parties and use it for their benefit.

Types Of Packet Sniffing

There are 3 types of packet sniffing, let us understand how they work:

IP Sniffing – It uses the network card to sniff all information packets that correspond with the IP address filter. These information packets are all used for analysis and examination.
MAC Sniffing – It also works through a network card and sniffs away the information packets that correspond to MAC address filter.
ARP Sniffing – In this type of sniffing, information packets are sent to the administrator through the ARP cache of both network hosts. The traffic is forwarded to the administrator directly instead of sending it to the hosts.

How To Protect Yourself From Packet Sniffing?

Use VPN – VPN (Virtual Private Network) connections provide complete privacy and secure your computer’s internet connection. It makes sure that all the data you are sending and receiving is encrypted & secured.
Always Check the HTTPS – Make sure that the websites that you visit have an HTTPS in its URL. Having it in the URL ensures that the website is safe to use.
Be Cautious – The risk of packet sniffing rises when a device is connected to a public Wi-Fi network. So be highly cautious of the websites you visit when you are on that network. Avoid doing financial transactions, entering sensitive information etc.
