Endpoint security
management is a policy-based approach to network security that requires
endpoint devices to comply with specific criteria before they are granted
access to network resources. Endpoints can include PCs, laptops, smartphones
and tablets, as well as wearables and specialized equipment such as bar code
readers, intelligent sensors and point of sale (POS) terminals.
Each endpoint in an
organization provides multiple attack vectors against the organization's
systems, networks and data. Although the perimeter firewall and end-user
awareness training remain an important part of defense-in-depth security, the
bulk of an organization's security efforts should focus on network endpoint
security controls.
The business
benefits of endpoint security management include decreasing the number of
data breaches and other incidents, easing the deployment of new security
technologies, reducing costs and blocking unwanted activity.
Endpoint security management software
Endpoint security
management systems, which can be purchased as software or as a dedicated
appliance, discover, manage and control computing devices that request access
to the corporate network. Endpoint security systems work on a client/server
model in which a centrally managed server or gateway hosts the security
program and an accompanying client program is installed on each network
device. In a software-as-a-service (SaaS) delivery model, the host server and
its security programs are maintained remotely by the vendor.
In either delivery
model, when a client attempts to log onto the network, the server program
validates user credentials. Required elements may include an approved
operating system, a VPN client and anti-virus software with current updates.
Devices that do not comply with policy are given limited access or
quarantined on a virtual LAN (VLAN). Endpoints that do not comply with policy
can be controlled by the system to varying degrees. For example, the system
may remove local administrative rights or restrict Internet browsing
capabilities.

In the ever-evolving landscape of artificial intelligence (AI) and machine learning (ML), one of the most intriguing advancements is the emergence of General AI (Gen AI). To grasp its significance, it's essential to first distinguish between these interconnected but distinct technologies. AI, ML, and Deep Learning: The Building Blocks Artificial Intelligence refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. Machine Learning, a subset of AI, empowers machines to learn from data and improve over time without explicit programming. Deep Learning, a specialized subset of ML, involves neural networks with many layers (hence "deep"), capable of learning intricate patterns from vast amounts of data. Enter General AI (Gen AI): Unraveling the Next Frontier Unlike traditional AI systems that excel in specific tasks (narrow AI), General AI aims to replicate human cognitive abilities across various domains.
