system security Linux network The romanticized image of the digital nomad – a laptop on a sun-drenched balcony – rarely accounts for the actual friction of maintaining a professional development environment on the move. . The friction is amplified with Linux. We are looking for a setup that respects our kernel configurations, handles volatile network handovers, and maintains a strict security posture without the hand-holding of a consumer-grade OS – so, put simply, more than just a laptop and a sunny deck. The hardware is...

Server Securityopen-source Linux administration
open-source Linux administration Cron has existed in Unix and Linux environments for decades, handling backups, cleanup scripts, patching jobs, log rotation, monitoring tasks, and other maintenance work that administrators do not want to run manually. Most Linux servers rely on it constantly, which is exactly why attackers continue abusing it for persistence after a system has already been compromised. . Persistence through cron is not complicated. Attackers do not need a rootkit or advanced malware framework to maintain...

security breach linux A major internal repository breach at GitHub has exposed a critical and overlooked blind spot in Linux supply chain security. Kernel exploits, exposed SSH services, weak firewall rules, and vulnerable daemons dominated the Linux threat model for years, and in many environments, they still matter. But recent supply-chain incidents involving GitHub ecosystems, npm packages, and malicious developer tooling point somewhere else entirely: the developer workstation. . The breach matters because...

Security Trends access control multi-tenant
access control multi-tenant Linux administrators often face an ugly choice in the cloud: prioritize convenience and cost-efficiency by sharing infrastructure, or sacrifice those benefits for the sake of total isolation. Most modern Linux workloads don't live on their own private servers anymore. They live in shared environments like Kubernetes clusters, where multiple teams and services run side-by-side. It sounds efficient, and it usually is. . But cloud isolation isn't as ironclad as it looks on the diagram. If you...

incident response cloud security Managed Extended Detection and Response (MXDR) has become one of the most sought-after security services in the enterprise market — and with good reason. It promises the holy grail: broad visibility across endpoints, network, cloud, email, and identity, combined with the 24/7 human expertise most organizations simply cannot build in-house. . However, the rapid growth of the market has produced a wide range of providers whose capabilities vary considerably beneath the surface. Choosing the...

security advisorydata protectione-commerceComodo's Ten Tips For Safe Online Shopping This Holiday Season
Comodo offers tips to experience e-commerce a safe and secure one this season. Never, under any circumstances, use a public network for financial transactions. Public networks include Internet cafes, coffee houses, public libraries and airports. Only send your personal and financial details over a network you've set up yourself, or one you know to be secure. Who knows what horrors are lurking on the hard disk of that internet. . JERSEY CITY, NJ, December 3, 2010 - Comodo, (www.comodo.com) a leading Internet security organization, is giving customers some sound security advice this holiday season with ten tips for remaining safe when purchasing your holiday gifts online. "Cyber-criminals are smarter and hungrier than ever to take advantage of those trusting individuals who don't take the necessary precautions to keep their information secure when purchasing those last minute gifts on the go," said Melih Abdulhayoglu, Comodo CEO and chief security architect. "These 10 very basic tips should help you from falling prey to such cyber-criminals looking to steal your credit card information or identity." These days the cyber world is becoming bigger and bigger with rapidly growing number of businesses and individuals using the Internet as a business place. Naturally, cyber-criminals target computers with low antivirus Internet security to commit their criminal activities. Here are Comodo's 10 tips to keep your e-commerce experience a safe one: 1. Never, under any circumstances, use a public network for financial transactions. Public networks include Internet cafes, coffee houses, public libraries and airports. Only send your personal and financial details over a network you've set up yourself, or one you know to be secure. Who knows what horrors are lurking on the hard disk of that internet. 2. Never, ever submit confidential data over a non-secure connection. Whenever you are about to login to a site you should always take a moment to first check whether the browser address bar starts withhttps rather than http. Even if you are on a https connection, never submit confidential information to a site if your browser displays a 'certificate error'. Such an error can be for many reasons, none of them good. It can mean the SSL certificate has expired, has been revoked (possibly for fraudulent behavior), is a self-signed certificate (the business behind the website has not been checked out by trusted third party) or because the domain listed on the certificate does not match the domain to which you are actually connected. 3. Use complex passwords for online logins (a different one for each site). Passwords should contain at least 8 characters with a combination of alpha numeric and special characters changed every 60 days (immediately if you suspect that it has been compromised), and should not contain your username or any other personal information associated with you. Passwords must NOT be written down on paper, stored electronically without encryption, sent over insecure e-mail, chat or SMS, or disclosed over phone or even in person. 4. Use added Internet security protection software. Using such software, like Comodo TrustConnect, can protect your data and privacy when shopping online or browsing the internet while at coffee shops, hotels, airports, libraries, or anywhere you're using the Internet, for both wired and wireless connections. 5. Disconnect from the Internet when not in use. Whenever your Internet is not in use just simply disconnect form Internet. It lessens the possibility of cyber-criminals passing your Internet security. 6. Avoid file sharing. Files from other computer users may contain malicious infections that, without a good anti-virus Internet security protection, can potentially destroy your computer or steal sensitive information. Make sure you turn off and disable file-sharing if it is not needed. 7. Update security patches. Computer programs sometimes contain bugs that may be exploited by a malicious person to attack and potentially harm your computer.Therefore, it is very important to regularly update your security patches and increase your safety. 8. Look for the Green. If you see the green bar at the top of your web browser URL, then you are good to go. The green bar Extended Validation is the next generation of SSL Certificate and was designed to strengthen e-commerce security and combat phishing attacks. The highly visible green address bar helps e-commerce merchants increase trust, reduce shopping cart abandonment, and build long-term revenue. 9. Prevent 'brute force' password cracking attempts. The password should not contain any words found in the English dictionary and should not repeat any previous passwords. You should also make a point of raNdoMLy switching between upper and lower case letters. Users can also greatly reduce the chances of their password being compromised by logging out of the website and closing the browser window after each secure session. 10. Look for 'Trust Marks' and customer feedback while on a merchant website. Look for those site seals like seller ratings from a trusted source, the Corner of TrustLogo, BuyerTrust, HackerProof, etc. Each of these site seals conveys a slightly different message of security but are all testaments to a merchant's trustworthiness.

Every year millions of dollars are lost to credit card fraud. Just who is supposed to be held responsible for all this stuff? The online shopping sites, the end user or your over friendly neighbour? In this article, I shall talk about the detailed anatomy of a credit card, the loop holes of some of the online shopping sites and a few other details. I will try to show you, the honest citizen, the Internet world through the eyes of a cracker. Believe me, some of the facts here can give sleepless nights to anyone who loves his/her hard earned money. Card number generating software such as CMaster4 are able to generate fake real-looking numbers. Even today, there are sites which process transactions only by checking the validity credit card number itself (not qwhether the number exists or not). Hard to believe, but 2-3 years ago, Mail.com used to only check for the credit card number and if it was found to be correct, the user would have access to platinum account with increased webspace. My research showed that only after a day would mail.com send you a reply back saying the details that you have entered are invalid... but by that time a malicious user has already used the paid service for free. During the recent french open event, rolandgarros.com had opened a merchandise site for selling items related to the event. The site used SSL but it did not bother to check the credit card number of the customer, only a small javascript was introduced in the web page for validating the card.

Last week I got e-mail from eToys, the online retailer that went out of business last spring. Signed "Your Friends at eToys," it recommended I now do all my toy shopping at KBkids.com, the company that bought eToys' remaining inventory for $5.4 million. Then my good friends at eToys made another suggestion: the letter asked me to approve the transfer of personal information I had given eToys to KBkids.com. My first reaction was to recoil in horror. Reveal my private personal information? No way. But then I read on and realized there was an incentive: "KBkids.com is offering you a special eToys Welcome Coupon good for $5 off one purchase of $30 or more at KBkids.com."

"Are the hackers getting better, or is it just that the people in charge of security at big Web companies are nodding off on the job? Online shoppers have reason to wonder after another in a series of intrusions into e-commerce sites that were supposed to have the best security money could buy. Online rare book store Bibliofind.com, a subsidiary of Amazon.com, this week revealed that hackers broke into its site, obtained credit card numbers for some 98,000 customers, and remained undetected for four months. Internet security has always been recognized as a big challenge, with countless hackers ever on the lookout for ways into secure databases. But weren't companies supposed to have their best and brightest at work on the problem in exchange for all those credit card numbers that trusting consumers handed over to them? The Bibliofind incident, following similar hacks at companies like Egghead.com and in-house breaches at Travelocity and Sony's Columbia House, raises new questions about whether Web companies are doing all they can to make their sites safe places to shop."

Dot-com businesses may be falling by the wayside, but the percentage of commerce happening via the Web continues to grow. Meanwhile, hundreds of millions of cellular subscribers worldwide are gaining access to new wireless data choices, including Web-enabled cell phones, handheld computers and PDAs. Combine these two facts, and you get an industry with an unbelievable potential called mobile commerce, or m-commerce. Not convinced? How about this: A woman is looking at a DVD player in a store and is ready to buy, but she isn't sure if the store is offering the best price. Using the microbrowser on her cell phone, she quickly determines that your online enterprise is selling the player for 10 percent less; she purchases it from you right then for delivery the next day. Or, you send your subscriber an alert on his Palm to let him know tickets have just gone on sale for one of his favorite performers, before the subscriber even knows the singer is coming to town. Within minutes, the customer selects the best seats in his price range and purchases tickets from you. The link for this article located at NWC is no longer available. .

To this day, I still receive junk mail from the company that tempted me back in college with its so-called 1-cent CD mail-order club. It's a fact of life, whether we shop online or in stores, that merchants will use customer information to the fullest extent.
