email security Linux server
email security Linux server You've probably trained your team to look for red flags. Odd sender names, urgent language, mismatched links. But a well-crafted spoofed email won't trip any of those wires. It looks legitimate, sounds legitimate, and often comes from a domain that passes every automated check you throw at it. . Attackers know exactly how humans scan an inbox. They design around it. This guide walks you through the techniques attackers use to slip a spoofed email past both your filters and your users and what...

Security Vulnerabilities cisa kev vulnerability prioritization
cisa kev vulnerability prioritization Most Linux teams don't struggle to find vulnerabilities anymore. They struggle to decide which ones deserve attention first. Between daily scanner results, vendor advisories, and hundreds of new CVEs each month, the challenge isn't visibility—it's prioritization. . To solve this, organizations typically lean on the National Vulnerability Database (NVD) and CISA’s Known Exploited Vulnerabilities Catalog. But these aren’t competing lists. They answer two entirely different questions. While the...

data privacy automation Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes. The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

Kevin Curran, an IT lecturer at the University of Ulster's Magee campus, said companies across the province using wireless computer networks were leaving themselves open to hackers who can use their systems to surf the net for free - even for accessing child pornography. As part of a research project, Mr Curran and a colleague were able to penetrate 15 company networks in Derry in a few hours using just a laptop, and discovered another five which could have been hacked with little effort. They used around £80 worth of other equipment, a wireless WiFi card and a magnetic mount omnidirectional antenna, which can be found at any computer store.

It is no secret that wireless local area networks, or WLANs Latest News about WLAN, can be probed by anyone within range of their radio signal, leaving them vulnerable to eavesdropping, unauthorized access and even viruses. In short, most WLANs have security loopholes large enough to drive a truck through. WEP (wired equivalent privacy), is the security mechanism that comes standard with 802.11 products, but its days are short-lived. That is because a new standard -- Wi-Fi Latest News about Wi-Fi protected access, or WPA -- is on the way. In the meantime, however, vendors are not waiting for certification; they are building products to bridge the time lag and give WLAN administrators solutions now. The No. 1 security problem for WLANs is that a large number of enterprises do not activate their existing security systems, says Meta Group senior analyst Chris Kozup. .

Enterprises are turning to WLANs in droves because they offer mobility and huge cost advantages. In fact, studies show that wireless workers are more productive, less pressured and save businesses money. Gartner, Inc., for instance, finds WLANs to be cheaper to install than wired LANs, especially for small organizations. And once they're in, wireless LANs are less expensive to operate and maintain. But wireless LANS are not everywhere they could be. Enterprises have heard the horror stories of competitors and crackers sitting in a parking lot and accessing the corporate network. Unfortunately most of these stories are true. Gartner predicts that by the end of this year, a third of all enterprises will suffer a serious security exposure due to a wireless LAN. The reason? The main protector of wireless LANs, the Wired Equivalent Privacy (WEP) standard, remains full of holes. Research from Cahners' In-Stat and META Group suggest the lack of security is the biggest deterrent to widespread adoption of WLANs.

IT managers are cautiously optimistic that wireless networks will - over time - become as secure as today's local area networks, but security concerns are still holding back deployment of the technology. Those are the main findings of a limited (but still informative) survey of IT security manager attitudes on the deployment of 802.11b (wireless) networks by security consultancy Defcom released this week. . .. IT managers are cautiously optimistic that wireless networks will - over time - become as secure as today's local area networks, but security concerns are still holding back deployment of the technology. Those are the main findings of a limited (but still informative) survey of IT security manager attitudes on the deployment of 802.11b (wireless) networks by security consultancy Defcom released this week . The 20 senior IT security managers questioned by Defcom at a recent London event were optimistic on the future security of WLAN equipment. Ninety per cent believed that it will be as secure as regular LANs within the next three to five years. However nearly two thirds (60 per cent) of the IT security managers polled said that the main barrier to wireless networking growth is still the perceived lack of securit. Wireless LAN sales growth remains strong. Recent research by Gartner Dataquest predicted worldwide WLAN shipments will grow by 73 per cent this year. Defcom's findings should encourage both manufacturers and the Wi-Fi standards body to properly address the fears of many end-users. Replacing the previous encryption standard, WEP (Wireless Equivalent Privacy), with more robust WiFi standards Wi-Fi Protected Access (WPA) is a step in the right direction but IT security managers are still sceptical. WPA uses a higher level of encryption and brings in dynamic key exchange functions absent with WEP. WPA is designed to work with existing products and is expected to first appear in Wi-Fi certified products during the first quarter of next year. Eighty per cent of IT security managersquestioned by Defcom said they did not trust the manufacturers of wireless networking solutions to provide security expertise, even after the announcement of WPA. One small step for security, one giant leap of the marketing kind User caution about WPA, which all concerned welcome as a big improvement on the broken WEP standard, is echoed by vendors who tell us WPA is far from the last word on wireless security. Wireless gateway vendor Bluesocket says WPA is a significant improvement over WEP as a security framework. But it is an incomplete, temporary solution until 802.11i is available at the end of 2003. 802.11i is the medium term goal for the Wi-Fi Alliance, but in promoting testing and interoperability work on WPA the industry is losing sight of some of its shortcomings, Bluesocket argues. Dave Juitt, CTO at Bluesocket, said enterprises are looking for bandwidth management, secure mobility and policy enforcement features but WPA only covers authentication and access control. "WPA only addressing one part of the puzzle. It won't solve all the problems even when its is deployed, which is not a given" Juitt told us. WEP frequently went unused by many enterprise users, some of whom left themselves vulnerable to war driving by not taking additional security measures (such as deploying wireless networks over VPNs). So will WPA be more widely used? Juitt reckons the short answer to that is yes, but he's not without his reservations. "WPA is less onerous than WEP, since it doesn't have as much involvement with mobile devices, but it doesn't fulfil everyone's needs. Interoperability might still be a barrier - it's not as simple as some people say," Juitt told us. WPA is positioned as being compatible with 802.11i when the enhanced standard becomes available. Bluesocket argues that 802.11i will require AES support in access points and therefore new hardware. New hardware is hardly a recipe for compatibility, it points out. . IT leaders are optimistic about enhancements in WLAN security;nevertheless, lingering apprehensions are slowing adoption, even as forecasts indicate significant growth..
