CWE - 2011 CWE/SANS Top 25 Most Dangerous Software Errors. Summary Discussion Salt might not be good for your diet, but it can be good for your password security.
Instead of storing passwords in plain text, a common practice is to apply a one-way hash, which effectively randomizes the output and can make it more difficult if (or when?) Attackers gain access to your password database. Stuxnet: How It Happened And How Your Enterprise Can Avoid Similar. A look back at one of the industry's most complex attacks -- and the lessons it teaches [Excerpted from "Stuxnet Reality Check: Are You Prepared For A Similar Attack," a new report posted this week on the Dark Reading Advanced Threats Tech Center.]
Iranian nuclear facilities, zero-day exploits, secret operatives and nation-state government involvement sounds more like the backstory to a spy novel than a piece of malware. Yet Stuxnet, the most researched and analyzed malware ever, is still being studied and discussed in security circles around the world -- even though it was discovered more than a year ago. You probably don’t operate a nuclear facility, so why should you care about a piece of software that targeted specific centrifuge models in particular nuclear plants in another part of the world? How would a Stuxnet-like attack affect your enterprise -- and what can you do to stop it? PCFS Paper FINAL DRAFT. ASA 5500 Series Next Generation Firewalls Compare Models. Cisco ASA firewalls protect networks of all shapes and sizes, with consistent security across hybrid infrastructures — physical, virtual, and cloud.
These solutions combine the most deployed firewall in the industry with a full complement of next-generation network security services. They protect corporate networks while providing employees with secure access to data — anytime, anywhere, using any device. Subscriptions and Information Technology Products : API Catalog. What is a Redline?
A redline document is a quick, easy way to compare all the changes between the active standard and the previous version. A redline shows additions, deletions, and other formatting and content changes between the two versions. Redlines ensure that you know exactly what changes have been made from one version to the next. Use Redlines To: Identify updates in minutes, not hours Effortlessly implement changes to procedures, equipment and products Save time and resources When you purchase Techstreet redlines, you receive TWO documents -- the clean, active version of the standard and the redline version.
Final Version of Industrial Control Systems Security Guide Published. The National Institute of Standards and Technology (NIST) has issued the final version of its Guide to Industrial Control Systems (ICS) Security (SP 800-82),* intended to help pipeline operators, power producers, manufacturers, air traffic control centers and other managers of critical infrastructures to secure their systems while addressing their unique performance, reliability, and safety requirements.
Finalized after three rounds of public review and comment, the guide is directed specifically to federally owned or operated industrial control systems (ICS), including those run by private contractors on behalf of the federal government. Examples include the mail handling operations, air traffic control towers, and some electricity generation and transmission facilities and weather observation systems. However, the guide's potential audience is far larger and more diverse than the federal government, since about 90 percent of the nation's critical infrastructure is privately owned. Security Updates in a 1-Way ICS? The good security practice for getting security updates to an ICS is well understood.
Handbook of Information Security Management:Communications Security. Application-Gateway Firewalls A second type of firewall handles the choke function of a firewall in a different manner — by determining not only whether but also how each connection through it is made.
This type of firewall stops each incoming (or outgoing) connection at the firewall, then (if the connection is permitted) initiates its own connection to the destination host on behalf of whomever created the initial connection. This type of connection is thus called a proxy connection. Using its data base defining the types of allowed connections, the firewall either establishes another connection (permitting the originating and destination host to communicate) or drops the original connection altogether. If the firewall is programmed appropriately, the whole process can be largely transparent to users. An application-gateway firewall is simply a type of proxy server that provides proxies for specific applications.
Network Access Control Policy. Please note that this policy has not yet been revised or converted to the new format. 1.
Preamble A key principle underpinning a high standard of IT Security is that access to computer network resources should be authorised on a ‘need to use’ basis. Historically, most computers connected to the University network have had full access to almost every other computer on the University network, and most staff computers have had full access to the Internet. The risk of compromise to Monash University computers can be reduced significantly without affecting normal use if the machines are segregated on the network according to their usage requirements. 2. The Network Access Control Policy defines the roles of Servers, Internet Servers and Client Computers when connected to the University’s network and defines permissible communications flows between them 3.

Thanks for visiting! The terms proxy firewall and gateway firewall are used synonymously. These firewalls help to maintain the transparency between the requester and server. As you know, the packet filter firewall inspects the headers of the packets, so it works at network transport layer. But to do inspection of packets at deeper level for better security, we need the proxy firewalls which works at application layer. Every packet entering your internal network passes through your firewall. Pg3-16.pmd - alrm1210.pdf.
