Serious Error
Dear, good morning. I would like to make clear in this discussion, the importance that we give the integrity of our data, in particular our emails. We constantly see people everywhere reporting infections on their desktops and applications, but I do not see reporting as contracted. Importance would be a good integrity of our emails because we feed them well (cybercriminals) with new weapons by obtaining data on which they should not. Social networks registered with corporate e-mail, blogs registered with corporate e-mail etc., make each day are more targeted. As security expert, I always make sure that after all always looking for a culprit for a serious infection or destructive, and at the end of everything as it always has to have a fault, this is a security solution, but we learn that , we have to create its own policy of security as well. Attached to this discussion, is a video explaining the step taken by an attacker to collect e-mails and perform intrusion attempts with new weapons all the time are created by these criminals. Remember, a cracker does not use steps "maldados," they create their own weapons and new weapons to attack, so we never have a 100% solution, but if you create a good security policy in yourself, then it will be secured 100%, because a good percentage depends on your security solution, and so another good percentage is up to you forever! I hope you enjoyed. Big hug to everyone.Solved3.1KViews1like12CommentsPhrases that scare security professionals
Given the findings of some practices and routines, it is easy to know what the problems are with the security companies. It is your case? The scenes are classic. A child with chocolate smeared shirt says, categorically: "It was not me." Or the phone rings and mother assures you, "There's nothing to worry about." Or a systems administrator who carries a box of tapes back up guarantees: "Within minutes, all information will be retrieved." In some cases, the first words you hear - despite the distance between them and the truth - are enough to tell you everything you need to know. In some cases, the first words you hear - despite the distance between Them and the truth - are enough to tell you everything you need to know. The same applies to the world of information security. The same applies to the world of information security. Some words sound reassuring, but we know they often point out problems of internal security, technical resources or the people and processes involved in the protection systems. Get to know some of the phrases "revealing secrets" that signal the imminence of problems in security. One. One We have a culture of safety We have a culture of safety "No, you do not have" is the immediate response of the professionals. "No, you have not's" is the immediate response of the professionals. Even if only mentally. Even if only mentally. This is the kind of phrase that comes from companies that started with five people - in the traditional family business model - and, as they grew, a snap themselves operating with thousands of people without governance or policies. This is the kind of phrase That comes from companies That started with five people - in the traditional family business model - and, As They grew to snap Themselves Thousands of people operating with or without governance policies. Some exchanged and its "safety culture" are enough to buy a good espresso in a quiet corner allowing look to the horizon and find out how much work lies ahead. Some Exchanged and its "safety culture" are enough to buy a good espresso in a quiet corner Allowing look to the horizon and find out how much work lies ahead. The simple fact is that without support guidelines or feedback mechanisms (feedback), security is defined differently by each and is not verified by anyone. The simple fact is without support guidelines That common mechanisms or feedback (feedback), security is defined differently by each and is not verified by anyone. There are no metrics for compliance with the "culture" and a "safety culture" is hidden by a practice of "do your job". If there are rules, write them down. If there are rules, write down Them. If technology is put into action to implement or monitor the rules, write that down too. If technology is put into action to Implement or monitor the rules, write down That too. If people break the rules, comply with what was agreed. If the rules undermine the legitimacy of the business when completed, change them. 2nd. 2nd. IT security is information security IT security is the security of information Information security is not the same thing in the information technology security. If the term "information security" is used in the same way that "IT security", it invariably means that nobody has taken decisions not primarily security techniques that affect departments - IT, human resources, legal, audit and perhaps others in the organization. Join those who have influence in the departments listed above and decide whether information (not paper documents or equipment) is an asset of the company, such as computers and desks. Decide whether the company authorizes people to do jobs, logical and physical access to information as individuals. Decides Whether the company authorizes people to the jobs, logical and physical access to the information Individuals. Take these policies in group decisions. Take these policies in group decisions. Then maybe there will be more time to decide "how to" manage security - rather than trying to guess ... 3rd. 3rd. This does not apply to the chief This does not apply to the chief Although this is becoming less of an issue in public, occasionally an executive simply refuses to follow security guidelines that he himself approved. Although this is less of an issue Becoming in public, occasionally an executive simply Refuses to follow security guidelines That he himself approved. Unless you are prepared to meticulously document all "escapades" following the model of forensics and then deliver them to the directors or the police (or just quit), be prepared to work around the situation. Most bad apples can be managed by applying the Machiavellian sense of having influence the relationship of the other: they must at least pretend to lead by example, while continuing to do whatever they do behind closed doors. Few will admit it, but many Organizations simply put in the budget and install a DSL line access to "guests" in the halls of top executives and Their Eyes close to anything that is plugged into That line. This is not a desirable solution, but if you still solve these executives sign the documents required by Sarbanes-Oxley, the rest comes from the ability to deny knowledge of security professionals. 4th. 4th. Our department gets information security IT staff Our department gets information security IT staff Titles do not matter. Titles of not matter. A report by a security expert at the IT director is always a security administrator, even if that person has the job of information security officer. The problem is that in the corporate world the word "officer" usually means that professional has the authority to verify and monitor whether all the techniques and processes that control proprietary information are efficient. An IT security administrator is usually involved in designing technical control and therefore can not be "self-audit" and make sure that IT is doing the right thing, particularly if it relates to someone within IT. The security professional with the position of "officer" should always report the same level or higher as the IT director. The security professional with the position of "officer" should always report the same level or higher to the IT director. 5th. 5th.

Although the idea to make the faint young student, ex ist indeed managers who demand That Their direct employees to Disclose Their individual passwords. The explanation for this is always: "What if someone is fired or sick? How could we find your documents?." When this happens, the only effective strategy is to tell anyone who asks such a thing: "If you do, then you are a suspect in any negative situation that arises. When this happens, the only effective strategy is to tell anyone who ASKs such a thing: " You'll never be Able to fire anybody because you will Also be a suspect. "Or you can always summarize it all in a simple:" Grow friend. " 7th. 7th. The brand is our standard I have nothing against the major hardware vendors in the market, but when the personal shopping company says: "Our standard is Dell" (or any other brand), what they are really saying is: "We play our standards security out the window in exchange for discounts and now we buy whatever the vendor offers.

But a manufacturer is not a technical standard and there is a problem in that mix if anyone does their homework. But the manufacturer is not a technical standard and there is a problem in That mix if anyone does Their homework. When a manufacturer makes changes in line or software product - especially when that part of an equipment manufacturer and network security such as Cisco Systems - it is important to have clearly defined functional requirements to assess whether the products still work as desired. When the customers not know what They want, any bargain Seems to be what you need. 8th. 8th. Hey, where did that come from? It is conceivable that those highly technical users should organize their own equipment as well as support them. On the other hand, this means that the area of IT and support personnel were knocked out by hardware manufacturers that provide only an 0800 number that never works. Security policies must be present everywhere, including the bathrooms attached to the wall behind the toilet paper of an organization. Security policy in the company can be exposed Also next to the bathroom towels. The important thing is to be clear and known to all. Solving this problem is a fundamental respect.

Start with the basic governance and making it clear that there are rules, with much effort and communication, this will at least make the "safety culture" a settled matter. 9th. 9th. We ship to the firewall rules ... Most network administrators cowers with the words mentioned above. Still, many will still send free email with a copy of the firewall rules. Worse, they have an OEM or a freelance consultant who set up the firewall for them and retain the single copy of the rules. These rules, if they present complexity, provide a detailed map of the security scheme of the company, with important information about the identity of internal networks and services and how to make them a target. No serious security professional would date a copy of the firewall rules of someone without a specific requirement to do so. A competent auditor of information systems certificate or other auditor will review firewall rules directly into the system administrator and can not take.

The risks of fraud in computer security or enterprise networks have grown considerably in Brazil and worldwide. Essas são algumas das conclusões de um estudo realizado pela Deloitte intitulado “Risk Intelligent governance in the age of cyber threats”. These are among the findings of a study conducted by Deloitte titled "Risk Intelligent governance in the age of cyber Threats." The study, which took into account other surveys to be drawn, points out that in 2011, organizations heard suffered an average of more than one successful cyberattack per week, which represents an increase of 44% compared to 2010. "Companies generally, should no longer be questioned about the possibility of such an attack happen. É bem provável que ele já esteja acontecendo”, destaca André Gargaro, sócio da área de Gestão de Riscos Empresariais da Deloitte. It is very likely that it is already happening, "says André Gargaro, a partner in the area of Enterprise Risk Management at Deloitte. The cyber attacks, the study indicates, may harm a business in various ways, from simple vandalizing the site, even to the shutdown of electronic fraud and intellectual property theft. In Brazil, Deloitte indicates, with the exception of the financial industry, preparation companies is still very reactive in relation to protection. Apenas depois da ocorrência de um evento considerável é que as corporações começam a se preocupar com medidas para evitar impactos de outros ataques. Only after the occurrence of an event is significant that corporations begin to worry about measures to avoid impacts to other attacks. "The ideal is to anticipate possible attacks through knowledge of their potential invaders and shapes how they act.

The Microso ft Windows users warned about possible attacks "man-in-the-middle" capable of stealing passwords from some wireless networks and VPNs (Virtual Private Networks). However, the company will not release an update to resolve the problem. This is not a security vulnerability that requires Microsoft to issue a security update, according to some security experts. "This issue is due to deficiencies cryptographic protocol MS-CHAP v2 and is driven by configuration changes." Rather than release a security patch, Microsoft recommends IT administrators to add PEAP (Protected Extensible Authentication Protocol) to protect passwords on VPN sessions. A support document describes how to configure servers and clients for PEAP. The MS-CHAP v2 is used to authenticate users based VPNs PPTP (Point-to-Point Tunneling Protocol). Windows includes an implementation of PPTP. The threat has been identified by researcher Moxie Marlinspike safely during hacker conference Defcon. The specialist even showed a tool that could be used in this type of invasion, Chapcrack. To use Chapcrack an attacker must first capture data packets to be transmitted via a VPN or Wi-Fi. The most likely scenario: a forgery of a legitimate point wireless, as in an airport, to find a VPN or other traffic and then attack him. Microsoft is not aware of any attacks that have used this feature, but acknowledged that the threat is real. "An attacker who successfully exploited these weaknesses could obtain cryptographic user credentials," said the company's advisory on Monday (20/8). "These credentials could be reused to authenticate the cracker on network resources, allowing the execution of any action you take on this network." As noted Marlinspike, MS-CHAP v2, which refers to the Windows NT SP4 and Windows 98, has been denounced as unsafe for years.477Views2likes0Comments
