Gartner: SSE is SASE minus the SD-WAN

TH Author , ,

SASE adoption has been skyrocketing since the start of the pandemic. Secure access service edge, a term Gartner coined in 2019, combines security and networking in a single, scalable, cloud-based platform that fits well in a world in which employees work from home and mostly access cloud-based apps and services.Now Gartner is pushing a new acronym. Turns out, companies might prefer to get their SASE without the “A” — just security service edge, or SSE. Gartner this month published a Magic Quadrant for SSE (something the company never did for SASE); it’s available from vendors listed in the report (here and here, for example).To read this article in full, please click here READ MORE HERE…

NSA urges businesses to adopt zero trust for network security

TH Author

The National Security Agency this week detailed recommendations for businesses to secure their network infrastructure against attacks, giving safe configuration tips for commonly used networking protocols and urging the use of basic security measures for all networks.The NSA’s report highlighted the importance of zero trust principles for network security, but the bulk of it covers specific steps network administrators should take to keep their infrastructure safe from compromise. Configuration tips for network admins include the use of secure, frequently changed passwords for all administrative accounts, limiting login attempts, and keeping potentially vulnerable systems patched and up-to-date. The report also describes safe configurations for SSH (secure shell), HTTP and SNMP (simple network management protocol).To read this article in full, please click here READ MORE HERE…

FCC looks into BGP vulnerabilities, in light of Russian hacking threat

TH Author ,

The FCC is launching an inquiry into security issues surrounding the Border Gateway Protocol (BGP), a widely used standard used to manage interconnectivity between large portions of the Internet.The move, announced Monday, was issued in response to “Russia’s escalating actions inside of Ukraine,” according to the commission’s notice of inquiry.BGP is, in essence, a method of ensuring that independently managed networks that make up the global internet are able to communicate with one another. Its initial design, which the FCC said is still in widespread use today, does not contain important security features, meaning that, simply by misconfiguring its own BGP information, a bad actor could potentially redirect Internet traffic wherever it sees fit. This could let that attacker send incorrect information to its targets, read and compromise login credentials, or simply shut down whichever kinds of traffic it wishes.To read this article in full, please click here READ MORE HERE…

Cisco IDs top 2022 security threats and what to do about them

TH Author , ,

2022 will be another busy year for enterprise incident responders as ransomware, supply chain and myriad zero-day attacks will continue to rise, according to Cisco’s Talos security experts.To help address the threats, the Cisco Talos team used a blog and online presentation to detail steps enterprises can take to defend themselves against the growing field of bad actors and also to point out lessons learned from recent damaging exploits such as the Log4j vulnerability and Microsoft Exchange server zero-day threats.Once, zero-day attacks were typically launched by state actors against service providers, but those days are gone, wrote Nick Biasini head of outreach at Cisco Talos in a blog about the security landscape in 2022. Now new, less experienced combatants seek out a broader range of targets, using less surgical attacks. “This has led to more risky behavior than we’ve seen historically, without as much regard for collateral damage,” he wrote.To read this article in full, please click here READ MORE HERE…

Zero trust requires clear architecture plans before changing core systems

TH Author ,

Zero trust touches everything: identity, applications, networks, data, and devices. The best approach is not to change everything all at once. Instead, start with the big picture.In our research, we’ve found the most successful organizations dedicated the first phase of their zero-trust initiatives to working out an architecture. They didn’t rush into deploying solutions as though starting with a greenfield.Everyone else dove in fast, mixing the foundational work on zero trust with one or more of the knock-on efforts: rearchitecting networks, security, and data management; buying tools; forming implementation teams and setting them to work. All those things need to happen, of course, but with zero trust, it pays to do a lot more thinking about how all the pieces will fit together before undertaking the changes needed, either at the architectural level or in the tool set.To read this article in full, please click here READ MORE HERE…

Cato adds fine-grained CASB controls to SASE platform

TH Author ,

SASE vendor Cato Networks is adding fine-grained cloud access security broker (CASB) controls to its platforms.When employees working from home or branch locations log into SaaS services such as Office 365 or Dropbox or Salesforce, a CASB gateway can track the applications employees access, where they log in from, and sometimes even what they do when using those applications.Previously, Cato only offered limited CASB controls, enabling companies to allow or prohibit the use of particular SaaS tools, says Dave Greenfield, Cato’s director of technology evangelism. Now, individual behaviors can be controlled. For example, users might be allowed to download documents from certain cloud file-sharing providers but can only upload documents to a company’s preferred platform.To read this article in full, please click here READ MORE HERE…

Log4j flaw needs immediate remediation

TH Author , ,

After nearly two years of adopting major network and security changes wrought by COVID-19 and hybrid work, weary IT network and security teams didn’t need another big issue to take care of, but they have one: Stemming potential damage from the recently disclosed vulnerability in open source Java-logging Apache Log4j software.  Log4j or Log4Shell has been around a long time—it was released in January, 2001—and is widely used in all manner of enterprise and consumer services, websites, and applications. Experts describe the system as an easy-to-use common utility to support client/server application development.To read this article in full, please click here READ MORE HERE…

How to buy SASE

TH Author

Wouldn’t it be great if there were a cloud-based service that combined networking and security so that users located anywhere could safely and efficiently access applications and data located anywhere? That’s the aim of SASE (rhymes with gassy). SASE isn’t a single product, but rather it’s an approach, a platform, a collection of capabilities, an aspiration.Gartner coined the term Secure Access Service Edge in a 2019 research report, and the name stuck. Vendors have been doing backflips trying to cobble together complete SASE offerings, which would include at a minimum software-defined WAN (SD-WAN), secure Web gateway (SWG), cloud access security broker (CASB), firewall-as-a-service (FWaaS) and zero trust network access (ZTNA).To read this article in full, please click here READ MORE HERE…

Cisco hit with software and physical issues

TH Author

Cisco Systems has been hit with an unusual double-whammy of issues, one of them in software and one in hardware.First, the more serious issue, a firewall flaw. Security researcher Positive Technologies, which hunts for security vulnerabilities, posted a warning that a vulnerability in Cisco firewall appliances could allow hackers to cause them to fail.The problem is in the Cisco Adaptive Security Appliance (ASA) and Cisco Firepower Threat Defense (FTD) firewalls. Forrester Research says there are more than a million of them deployed worldwide. Positive assessed the severity level of vulnerability as high and recommended users should install updates, which are available, as soon as possible.To read this article in full, please click here READ MORE HERE…
