AWS secures access to cloud apps without using VPNs

TH Author , , ,

Amazon Web Services has launched a service that secures user access to its cloud applications without requiring a VPN.AWS Verified Access, which the company previewed last November, validates every application request using Zero Trust principles before granting access to applications. Since AWS previewed the networking service, it has added two new features: AWS Web Application Firewall (WAF) and the ability to pass signed identity context to customers’ application endpoints.To read this article in full, please click here READ MORE HERE…

Work from home is here to stay, so how should IT adjust?

TH Author , , , , , , ,

The pandemic has changed how we work, probably forever. Most employees with jobs that can be done effectively from home have no intention of returning full time to the office. They find that their work-life balance is much more balanced without the long commutes and constant interruptions that accompany office work.According to a McKinsey/Ipsos survey, 58 percent of American workers had the opportunity to work from home at least one day a week in 2022, while 38 percent were not generally required to be in the office at all.To read this article in full, please click here READ MORE HERE…

What is Zero Trust Network Architecture (ZTNA)?

TH Author , ,

Zero Trust is a term coined by John Kindervag while he was an analyst at Forrester Research to describe a strategic framework in which nothing on the network is trusted by default – not devices, not end users, not processes. Everything must be authenticated, authorized, verified and continuously monitored.The traditional approach to security was based on the concept of “trust, but verify.” The weakness of this approach is that once someone was authenticated, they were considered trusted and could move laterally to access sensitive data and systems that should have been off-limits.Zero Trust principles change this to “never trust, always verify.” A Zero Trust architecture doesn’t aim to make a system trusted or secure, but rather to eliminate the concept of trust altogether. Zero Trust security models assume that an attacker is present in the environment at all times. Trust is never granted unconditionally or permanently, but must be continually evaluated.To read this article in full, please click here READ MORE HERE…

How to set up DHCP failover on Windows Server

TH Author , ,

Redundancy is essential for dealing with both planned and unplanned outages, and that includes having redundant dynamic host-configuration protocol (DHCP) servers to allow uninterrupted dynamic assignment of IP addresses.For those working in Windows environments, there are currently two options for setting up redundant DHCP servers: a failover scenario with a main server paired with another in hot standby; and a load-balancing scenario in which two DHCP servers actively handle client requests.

5 mistakes to avoid when implementing zero-trust

TH Author ,

Interest in zero-trust security has heightened significantly over the past two years among organizations looking for better ways to control access to enterprise data in cloud and on-premises environments for remote workers, contractors and third parties.Several factors are driving the trend, including increasingly sophisticated threats, accelerated cloud adoption and a broad shift to remote and hybrid work environments because of the pandemic. Many organizations have discovered that traditional security models where everything inside the perimeter is implicitly trusted, does not work in environments where perimeters don’t exist and enterprise data and the people accessing it are increasingly distributed and decentralized.To read this article in full, please click here READ MORE HERE…

Who is selling Zero Trust Network Access (ZTNA) and what do you get?

TH Author , , , , , ,

Enterprise interest in Zero Trust Network Access (ZTNA) has soared over the past two years among organizations trying to enable secure anywhere, anytime, any device access to IT resources for employees, contractors and third parties.Much of this interest has stemmed from organizations looking to replace VPNs as the primary remote access mechanism to their networks and data. But it is also being driven by organizations seeking to bolster security in an environment where enterprise data is scattered across on-premises and multi-cloud environments, and being accessed in more ways than ever before.To read this article in full, please click here READ MORE HERE…

8 questions to ask vendors about Zero Trust Network Access (ZTNA)

TH Author ,

The increased deployment of core business applications in the cloud and the shift to remote work brought on by the pandemic have obliterated any notion of the traditional “corporate moat” style of security.Today’s hybrid workplace, where employees are on the road, working from home and maybe visiting the office once or twice a week, has forced network and security teams to adopt a more flexible approach to managing the network, identities, and authentication.Zero Trust Network Access (ZTNA) has emerged as the preferred approach to address today’s security challenges. The concept is relatively simple: Instead of building a layered perimeter defense of firewalls, IDS/IPSes and anti-virus software, Zero Trust assumes that every user or device is untrusted until it becomes sufficiently verified.To read this article in full, please click here READ MORE HERE…

What is NAC and why is it important for network security?

TH Author , , , ,

Network Access Control (NAC) is a cybersecurity technique that prevents unauthorized users and devices from entering private networks and accessing sensitive resources. Also known as Network Admission Control, NAC first gained a foothold in the enterprise in the mid-to-late 2000s as a way to manage endpoints through basic scan-and-block techniques.As knowledge workers became increasingly mobile, and as BYOD initiatives spread across organizations, NAC solutions evolved to not only authenticate users, but also to manage endpoints and enforce policies.How NAC works
NAC tools detect all devices on the network and provide visibility into those devices. NAC software prevents unauthorized users from entering the network and enforces policies on endpoints to ensure devices comply with network security policies. NAC solutions will, for instance, make sure that the endpoint has up-to-date antivirus and anti-malware protections.To read this article in full, please click here READ MORE HERE…
