ZTNA (Zero Trust Network Access)

Public keys are cryptographic keys used in cybersecurity to provide secure communication. It is a form of asymmetric cryptography, meaning that two different keys are used: one for encryption (public key) and one for decryption (private key). The public key is shared publicly and can be used to encrypt messages or data. The private key must remain a secret and is then used to decrypt the encrypted message or data. Public keys help ensure that only the intended recipient can read the message, as only they possess the private key needed to decrypt it. In cyber security, public keys are often used to authenticate users or encrypt communications between parties.

A CASB (Cloud Access Security Broker) is a security solution that helps protect data stored in cloud services. It monitors and enforces policies to ensure the safety of any data going in, out and within cloud applications. By using machine learning and analytics, it detects risky behavior and blocks suspicious activities. This provides an extra layer of protection, allowing businesses to maintain compliance while providing secure access to cloud applications. With a CASB, you can control who accesses your apps, what they can do with them and when they can do it from anywhere.

Software-defined Networking (SDN) is a revolutionary way for networks to be managed and operated. It separates the network control plane from the data forwarding plane, allowing for more flexibility and control. This helps enable automated networking processes, better security measures, and improved performance. SDN is used by organizations that require high levels of agility in their networks, such as those involving large enterprises or cloud computing applications. SDN also benefits cyber security by providing visibility into network traffic and giving administrators more control over how data is routed through the network. This means organizations can better protect themselves from malicious attacks and respond quickly to threats.

802.1x Access Control List (ACL) is a security protocol that enables secure access to networks, devices and applications. It is used to control access by allowing or denying certain types of traffic at the user level. ACLs can be used to identify, authenticate and authorize users, allowing them access only to specific resources they are authorized to use. It helps protect against unauthorized access, data theft and malicious activity on networks. Use of 802.1x ACL provides an extra layer of protection for data and resources within a network environment.

Layer 3 hardware is a type of network hardware that is used to read and forward data across a network. It works by reading the IP addresses contained within each packet of data and forwarding them to their destination. Layer 3 hardware is most commonly used in corporate networks, but can also be integrated into home networks for increased security. Layer 3 hardware helps protect against cyberattacks by authenticating users before allowing access to the network, and by detecting malicious traffic before it reaches its intended destination. It also offers additional features like Quality of Service (QoS) for prioritizing important traffic, as well as features like Network Address Translation (NAT) for hiding private IP addresses from public view. By providing these extra layers of protection, Layer 3 hardware helps ensure that data remains secure while it is transferred across the network.
