Durham County goes Cisco for enterprise network ops and security proficiency

The government in Durham County, N.C., was spending hours and hours manually provisioning its network and keeping security policies current, so it decided two and a half years ago to upgrade for the sake of efficiency and security.Since then, the government’s IT staff of four has migrated its traditional point-to-point network to a more modern enterprise featuring the software-defined technologies of Cisco’s Application Centric Infrastructure (ACI) and DNA Center that support its 2,100 enterprise end users and online services for 315,000 county residents.

DNS over HTTPS seeks to make internet use more private

Unauthorized interception of DNS traffic provides enough information to ascertain internet users’ thoughts, desires, hopes and dreams. Not only is there concern for privacy from nearby nosey neighbors, but governments and corporations could use that information to learn about individuals’ internet behavior and use it to profile them and their organization for political purposes or target them with ads. Efforts like the DNS Privacy Project aim to raise awareness of this issue and provide pointers to resources to help mitigate these threats.To read this article in full, please click here(Insider Story) READ MORE HERE…

What is Transport Layer Security (TLS)?

Despite the goal of keeping Web communications private, flaws in the design and implementation of Transport Layer Security have led to breaches, but the latest version – TLS 1.3 – is an overhaul that strengthens and streamlines the crypto protocol.What is TLS?
TLS is a cryptographic protocol that provides end-to-end communications security over networks and is widely used for internet communications and online transactions. It is an IETF standard intended to prevent eavesdropping, tampering and message forgery. Common applications that employ TLS include Web browsers, instant messaging, e-mail and voice over IP.To read this article in full, please click here READ MORE HERE…

What is a firewall? How they work and all about next-generation firewalls

A firewall is a network device that monitors packets going in and out of networks and blocks or allows them according to rules that have been set up to define what traffic is permissible and what traffic isn’t.There are several types of firewalls that have developed over the years, becoming progressively more complex over time and taking more parameters into consideration when determining whether traffic should or should not be allowed to pass. The most modern are commonly known as next-generation firewalls (NGF) and incorporate many other technologies beyond packet filtering.[ Also see What to consider when deploying a next generation firewall. | Get regularly scheduled insights by signing up for Network World newsletters. ]
Initially placed at the boundaries between trusted and untrusted networks, firewalls are now also deployed to protect internal segments of networks, such as data centers, from other segments of organizations’ networks.To read this article in full, please click here READ MORE HERE…

The best enterprise level firewalls: Rating 10 top products

You know you need to protect your company from unauthorized or unwanted access. You need a network-security tool that examines the flow of packets in and out of the enterprise, governed by rules that decide whether that flow is safe, malicious or questionable and in need of inspection. You need a firewall.Recognizing that you need a firewall is the first – and most obvious — step. The next crucial step in the decision-making process is determining which firewall features and policies best-suit your company’s needs.Today’s enterprise firewalls must be able to secure an increasingly complex network that includes traditional on-premises data center deployments, remote offices and a range of cloud environments. Then you have to implement and test the firewall once it’s installed. Perhaps the only element more complex than configuring, testing and managing a next-generation firewall is the decision-making process regarding which product to trust with your enterprise security.To read this article in full, please click here(Insider Story) READ MORE HERE…

IDG Contributor Network: Identity awareness: it’s more than just a packet

It was about 20 years ago when I plugged my first Ethernet cable into a switch. It was for our new chief executive officer. Little did she know that she was about to share her traffic with most others on the first floor. At that time being a network engineer, I had five floors to be looked after.Having a few virtual LANs (VLANs) per floor was a common design practice in those traditional days. Essentially, a couple of broadcast domains per floor were deemed OK. With the VLAN-based approach, we used to give access to different people on the same subnet. Even though people worked at different levels but if in the same subnet, they were all treated the same.To read this article in full, please click here READ MORE HERE…
