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...

security advisorydenial of servicehigh severityBind: High Severity Advisory for DoS Attacks - CVE-2023-2828, CVE-2023-2911
Several remotely exploitable security issues were found in the Bind Internet Domain Name Server. It was discovered that Bind incorrectly handled the cache size limit (CVE-2023-2828) and the recursive-clients quota (CVE-2023-2911). With a low attack complexity and a high availability impact, these bugs have received a National Vulnerability Database severity rating of “High”. . A remote attacker could possibly use these issues to consume memory or to cause Bind to crash, resulting in a denial of service (DoS). An important Bind security update that fixes these DoS bugs has been released. We strongly recommend that all impacted users apply the Bind updates issued by their distro(s) now to prevent downtime due to an attack.

security advisorycriticalmicrosoftMicrosoft And Juniper: Critical IPv6 DoS Attack Risk Advisory
Security experts are urging Microsoft and Juniper to patch a year-old IPv6 vulnerability so dangerous it can freeze any Windows machine on a LAN in a matter of minutes.. Microsoft has downplayed the risk because the hole requires a physical connection to the wired LAN. Juniper says it has delayed a patch because the hole only affects a small number of its products and it wants the IETF to fix the protocol instead. The vulnerability was initially discovered in July 2010 by Marc Heuse, an IT security consultant in Berlin. He found that products from several vendors were vulnerable, including all recent versions of Windows, Cisco routers, Linux and Juniper The link for this article located at Network World is no longer available. .

denial of servicehackingsecurity impactResearch on DoS Attacks and Their Effects on Internet Security
Joseph Idziorek, graduate in electrical and computer engineering, has been researching computer security. The study conducts research on sites that have been experiencing denial of service attacks, in which hackers try to get unauthorized access and hinder them.. An example of this is WikiLeaks, where the site was hacked after releasing documents of U.S. State Department cables that were considered classified information. "The purpose of such an attack is to bring down the website so nobody can use it," Idziorek said. "These have been quite prevalent throughout the Internet for the last 15 years since the Internet has been around." The link for this article located at iowa State Daily is no longer available. .

Forget spam, viruses, worms, malware and phishing. These threats are apparently old school when compared to a new class of denial-of-service (DOS) attacks that threaten wireless data networks. The latest wireless network threats were outlined in a talk here Thursday by Krishan Sabnani, vice president of networking research at Bell Labs, at the Cyber Infrastructure Protection Conference at City College of New York. . Sabnani said the latest wireless data network threats are the result of inherent weaknesses in Mobile IP, a protocol that uses tunneling and complex network triangulation to allow mobile devices to move freely from one network to another.

security advisorydos attackipv6IETF: Mitigating IPv6 RH0 DoS Amplification Vulnerabilities Effectively
This week, experts sent two drafts to the Internet Engineering Task Force (IETF)the technical standards-setting body for the Internet proposing different ways of fixing a problem in the way that Internet Protocol version 6 (IPv6) allows the source of network data to determine its path through the network. The drafts recommend that the IPv6 feature should either be eliminated or, at the very least, disabled by default. . The specification, known as the Type 0 Routing Header (RH0), allows computers to tell IPv6 routers to send data by a specific route. Originally envisioned as a way to let mobile users to retain a single IP for their devices, the feature has significant security implications. During a presentation at the CanSecWest conference on April 18, researchers Philippe Biondi and Arnaud Ebalard pointed out that RH0 support allows attackers to amplify denial-of-service attacks on IPv6 infrastructure by a factor of at least 80.
