Which technology prevents a person in the network from sending sensitive information outside the Organisation?

Data loss prevention tools can help infosec manage insider threat, shadow IT and compliance initiatives. Test your know-how with this DLP quiz.

Increasingly complex IT environments, combined with a sophisticated threat landscape and the continued expansion of remote work, have made the challenge of enterprise data security more daunting than ever for infosec teams.

There is no shortage of technology suites and tools available for IT leaders to divert precious security budget resources to ensure data protection. However, technology investment alone will not suffice to effectively prevent sensitive or proprietary data loss, corruption or theft.

Having a concrete data loss prevention (DLP) strategy in place is one the most effectual methods of detecting risks to valuable data. This set of technologies, products and processes monitors for anomalous behaviors and other indicators of insider threat or shadow IT. It is critical that infosec leaders and practitioners comprehend DLP features, controls and policies to ensure the organization is getting the most out of its security investments and programs.

With an understanding of DLP best practices -- as well as the importance of DLP in a cybersecurity strategy -- organizations are better equipped to prevent data exfiltration and breaches. Take this DLP quiz, specially designed with questions and answers about DLP, to measure and multiply your knowledge of this important data security tool and strategy.

What network security features prevent users on a network from using program and information that they do not need to access?

Firewall. Firewalls control incoming and outgoing traffic on networks, with predetermined security rules. Firewalls keep out unfriendly traffic and is a necessary part of daily computing.

What is a firewall in a computer network?

A firewall is a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules. Firewalls have been a first line of defense in network security for over 25 years.

How does a firewall protect a network?

A firewall can help protect your computer and data by managing your network traffic. It does this by blocking unsolicited and unwanted incoming network traffic. A firewall validates access by assessing this incoming traffic for anything malicious like hackers and malware that could infect your computer.

What is the purpose of a firewall?

What do firewalls do? Firewalls provide protection against outside cyber attackers by shielding your computer or network from malicious or unnecessary network traffic. Firewalls can also prevent malicious software from accessing a computer or network via the internet.
