Unfortunately, any application may contain holes, or vulnerabilities, that attackers can use to infiltrate your network. Application security encompasses the hardware, software, and processes you use to close those holes. To detect abnormal network behavior, you must know what normal behavior looks like. Behavioral analytics tools automatically discern activities that deviate from the norm. Your security team can then better identify indicators of compromise that pose a potential problem and quickly remediate threats.

Cloud security is a broad set of technologies, policies, and applications applied to defend online IP, services, applications, and other imperative data. It helps you better manage your security by shielding users against threats anywhere they access the internet and securing your data and applications in the cloud. Organizations must make sure that their staff does not send sensitive information outside the network.

Data loss prevention, or DLP, technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner. Email gateways are the number one threat vector for a security breach.

Attackers use personal information and social engineering tactics to build sophisticated phishing campaigns to deceive recipients and send them to sites serving up malware.

An email security application blocks incoming attacks and controls outbound messages to prevent the loss of sensitive data. Cybercriminals are increasingly targeting mobile devices and apps. Within the next three years, 90 percent of IT organizations may support corporate applications on personal mobile devices.

Of course, you need to control which devices can access your network. You will also need to configure their connections to keep network traffic private. SIEM products pull together the information that your security staff needs to identify and respond to threats.

These products come in various forms, including physical and virtual appliances and server software. A web security solution will control your staff's web use, block web-based threats, and deny access to malicious websites. It will protect your web gateway on site or in the cloud.

Wireless networks are not as secure as wired ones. Without stringent security measures, installing a wireless LAN can be like putting Ethernet ports everywhere, including the parking lot. To prevent an exploit from taking hold, you need products specifically designed to protect a wireless network.

Firewalls Firewalls put up a barrier between your trusted internal network and untrusted outside networks, such as the Internet. Email security Email gateways are the number one threat vector for a security breach. Anti-virus and anti-malware software "Malware," short for "malicious software," includes viruses, worms, Trojans, ransomware, and spyware. Network segmentation Software-defined segmentation puts network traffic into different classifications and makes enforcing security policies easier.

Access control Not every user should have access to your network. Application security Any software you use to run your business needs to be protected, whether your IT staff builds it or whether you buy it. Behavioral analytics To detect abnormal network behavior, you must know what normal behavior looks like.
