Cyber espionage

Cyber spying or Cyber espionage is the act or practice of obtaining secrets without the permission of the holder of the information (personal, sensitive, proprietary or of classified nature), from individuals, competitors, rivals, groups, governments and enemies for personal, economic, political or military advantage using illegal exploitation methods on the Internet, networks or individual computers through the use of cracking techniques and malicious software including Trojan horses and spyware. It may wholly be perpetrated online from computer desks of professionals on bases in far away countries or may involve infiltration at home by computer trained conventional spies and moles or in other cases may be the criminal handiwork of amateur malicious hackers and software programmers.
Cyber spying typically involves the use of such illegally gained access to secrets and classified information or illegally gained control of individual computers or whole networks for an unethical and illegal strategic advantage and for psychological, political and physical subversion activities and sabotage. More recently, cyber spying invovles analysis of public activity on social networking sites like Facebook and Twitter

Cyber espionage Threat of 2012 computer security

Cyber espionage (also spelled cyberespionage) involves the unauthorized probing to test a target computer’s configuration or evaluate its system defenses, or the unauthorized viewing and copying of data files.
Cyber-espionage, along with privacy violations and social networking attacks facilitated by the increased use of mobile and tablet devices, will be the source of increased security threats over the coming months, according to PandaLabs.
Cyber-espionage targeting companies and government agencies around the world will dominate corporate and national information security landscapes, with the integrity of classified and other protected information on the line. Trojans are expected to be the weapon of choice for hackers focused on these highly-sensitive targets.
According to Luis Corrons, technical director of PandaLabs, "We live in a world where all information is in digital form and is easily accessible if you know how. Today's spies no longer need to infiltrate a building to steal information. As long as they have the necessary computer skills, they can wreak havoc and access even the best-kept secrets of organizations without ever leaving their homes."
Consumers will continue to be targeted by cyber-criminals as they find ever more sophisticated ways to target social media sites for stealing personal data. Social engineering techniques exploiting users' naivete have become the weapon of choice for hackers targeting personally-identifiable information.
"Social networking sites provide a space where users feel safe as they interact with friends and family. The problem is that attackers are creating malware that takes advantage of that false sense of security to spread their creations," says Corrons. "It is very easy for cyber-criminals to trick users with generic messages like 'Look, you're on this video,' for example. Sometimes, curiosity can be our own worst enemy."


 major security trends of 2012:
Mobile malware: A year ago, PandaLabs predicted a surge in cyber attacks on mobile phones, and the fact that Android has become the number one mobile target for cyber-crooks in 2011 confirms that prediction. That trend will continue in 2012, with a new focus on mobile payment methods using Near-Field Communications (NFC) as these applications become increasingly popular.
Malware for tablets: Since tablets share the same operating system as smartphones, they are likely be targeted by the same malware. In addition, tablets might draw a special interest from cyber-crooks since people are using them for an increasing number of activities and are more likely to store sensitive data.
Mac malware: As the market share of Mac users continues to grow, the number of threats will grow as well. Fortunately, Mac users are now more aware that they are not immune to malware attacks and are increasingly using antivirus programs to protect themselves. The number of malware specimens for Mac will continue to grow in 2012, although still at a slower rate than for PCs.
PC malware: PC malware has grown exponentially over the past few years, and everything indicates that the trend will continue in 2012. Trojans, designed to sit silently on users' computers, stealing information and transmitting it back to their handlers, will continue to be cyber-crooks' weapon of choice; 75 percent of new malware strains in 2011 were Trojans.
SMBs under attack: Financial institutions are fairly well protected these days against malware. But smaller businesses are easier and cheaper targets to attack, and their customer databases can be a real treasure trove for hackers, particularly if credit card and other financial data is stored "in the clear." Unfortunately, many small to medium-sized companies do not have dedicated security teams, which makes them much more vulnerable.
Windows 8: While not scheduled until November 2012, the anticipated next version of Microsoft's operating system will offer cyber-crooks new opportunities to create malicious software. Windows 8 will allow users to develop malware applications for virtually any device (PCs, tablets and smartphones) running this platform, although this will likely not take place until 2013.

Computer Operations Security

Operations security and controls safeguard information assets while the data is resident in the computer or otherwise directly associated with the computing environment. The controls address both software and hardware as well as such processes as change control and problem management. Physical controls are not included and may be required in addition to operations controls.
Operations security and controls can be considered the heart of information security because they control the way data is accessed and processed. No information security program is complete without a thoroughly considered set of controls designed to promote both adequate and reasonable levels of security. The operations controls should provide consistency across all applications and processes; however, the resulting program should be neither too excessive nor too repressive.
Resource protection, privileged-entity control, and hardware control are critical aspects of the operations controls. To understand this important security area, managers must first understand these three concepts. The following sections give a detailed description of them.


RESOURCE PROTECTION
Resource protection safeguards all of the organization’s computing resources from loss or compromise, including main storage, storage media (e.g., tape, disk, and optical devices), communications software and hardware, processing equipment, standalone computers, and printers. The method of protection used should not make working within the organization’s computing environment an onerous task, nor should it be so flexible that it cannot adequately control excesses. Ideally, it should obtain a balance between these extremes, as dictated by the organization’s specific needs.
This balance depends on two items. One is the value of the data, which may be stated in terms of intrinsic value or monetary value. Intrinsic value is determined by the data’s sensitivity — for example, health- and defense-related information have a high intrinsic value. The monetary value is the potential financial or physical losses that would occur should the data be violated.
The second item is the ongoing business need for the data, which is particularly relevant when continuous availability (i.e., round-the-clock processing) is required.
When a choice must be made between structuring communications to produce a user-friendly environment, in which it may be more difficult for the equipment to operate reliably, and ensuring that the equipment is better controlled but not as user friendly (emphasizing availability), control must take precedence. Ease of use serves no purpose if the more basic need for equipment availability is not considered.
Resource protection is designed to help reduce the possibility of damage that might result from unauthorized disclosure and alteration of data by limiting opportunities for misuse. Therefore, both the general user and the technician must meet the same basic standards against which all access to resources is applied.
A more recent aspect of the need for resource protection involves legal requirements to protect data. Laws surrounding the privacy and protection of data are rapidly becoming more restrictive. Increasingly, organizations that do not exercise due care in the handling and maintenance of data are likely to find themselves at risk of litigation. A consistent, well-understood user methodology for the protection of information resources is becoming more important to not only reduce information damage and limit opportunities for misuse but to reduce litigation risks.


Accountability
Access and use must be specific to an individual user at a particular moment in time; it must be possible to track access and use to that individual. Throughout the entire protection process, user access must be appropriately controlled and limited to prevent excess privileges and the opportunity for serious errors. Tracking must always be an important dimension of this control. At the conclusion of the entire cycle, violations occurring during access and data manipulation phases must be reported on a regular basis so that these security problems can be solved.
Activity must be tracked to specific individuals to determine accountability. Responsibility for all actions is an integral part of accountability; holding someone accountable without assigning responsibility is meaningless. Conversely, to assign responsibility without accountability makes it impossible to enforce responsibility. Therefore, any method for protecting resources requires both responsibility and accountability for all of the parties involved in developing, maintaining, and using processing resources.
An example of providing accountability and responsibility can be found in the way some organizations handle passwords. Users are taught that their passwords are to be stored in a secure location and not disclosed to anyone. In some organizations, first-time violators are reprimanded; if they continue to expose organizational information, however, penalties may be imposed, including dismissal.

Defense in depth...IT SECURITY

Information security must protect information throughout the life span of the information, from the initial creation of the information on through to the final disposal of the information. The information must be protected while in motion and while at rest. During its lifetime, information may pass through many different information processing systems and through many different parts of information processing systems. There are many different ways the information and information systems can be threatened. To fully protect the information during its lifetime, each component of the information processing system must have its own protection mechanisms. The building up, layering on and overlapping of security measures is called defense in depth. The strength of any system is no greater than its weakest link. Using a defence in depth strategy, should one defensive measure fail there are other defensive measures in place that continue to provide protection.
Recall the earlier discussion about administrative controls, logical controls, and physical controls. The three types of controls can be used to form the basis upon which to build a defense-in-depth strategy. With this approach, defense-in-depth can be conceptualized as three distinct layers or planes laid one on top of the other. Additional insight into defense-in- depth can be gained by thinking of it as forming the layers of an onion, with data at the core of the onion, people the next outer layer of the onion, and network security, host-based security and application security forming the outermost layers of the onion. Both perspectives are equally valid and each provides valuable insight into the implementation of a good defense-in-depth strategy.
Security classification for information
An important aspect of information security and risk management is recognizing the value of information and defining appropriate procedures and protection requirements for the information. Not all information is equal and so not all information requires the same degree of protection. This requires information to be assigned a security classification.
The first step in information classification is to identify a member of senior management as the owner of the particular information to be classified. Next, develop a classification policy. The policy should describe the different classification labels, define the criteria for information to be assigned a particular label, and list the required security controls for each classification.
Some factors that influence which classification information should be assigned include how much value that information has to the organization, how old the information is and whether or not the information has become obsolete. Laws and other regulatory requirements are also important considerations when classifying information.
The type of information security classification labels selected and used will depend on the nature of the organisation, with examples being:
 In the business sector, labels such as: Public, Sensitive, Private, Confidential.
 In the government sector, labels such as: Unclassified, Sensitive But Unclassified, Restricted, Confidential, Secret, Top Secret and their non-English equivalents.
 In cross-sectoral formations, the Traffic Light Protocol, which consists of: White, Green, Amber and Red.
All employees in the organization, as well as business partners, must be trained on the classification schema and understand the required security controls and handling procedures for each classification. The classification of a particular information asset has been assigned should be reviewed periodically to ensure the classification is still appropriate for the information and to ensure the security controls required by the classification are in place.
