Cyber security involves protecting networks, computers, programs, and data from damage, unauthorized access, and impairment. It includes securing physical access to hardware and protecting against network attacks, data and code injection, and misuse by operators. As cyber attacks increase daily, nations face higher risks, so cyber security is a growing priority. Hacking, child pornography, copyright infringement, and other cybercrimes harm people's and nations' security and financial well-being. Effective cyber security incorporates measures across applications, information, networks, and disaster recovery to detect and prevent illegal computer use and ensure confidentiality, integrity, and availability of data. National cyber security policies aim to safeguard information systems and critical infrastructure through public-private cooperation and awareness

As more business activities are being automated and an increasing number of computers are being used to store sensitive information, the need for secure computer systems becomes more apparent. This need is even more apparent as systems and applications are being distributed and accessed via an insecure network, such as the internet. The internet itself has become critical for governments, companies, financial institutions, and millions of everyday users. Networks of computers support a multitude of activities whose loss would all cripple these organizations. As a consequences Cyber Security issues have become national security issues. Protecting the internet is a very difficult task. Cyber Security can be obtained only through systematic development. P. H. Gopi Kannan | A. Karthik | M.

Critical infrastructure cybersecurity is important to protect essential services from attacks. Some keys to effective protection are not limiting security to operational technology, taking an operational approach, integrating information technology and operational technology, and thinking globally and acting locally. In 2016, hackers accessed control systems at a New York dam during maintenance but did not release water. Various sectors like banking, healthcare, transportation, and government face cyber threats, so identity management, endpoint security, zero-trust network access, data loss prevention, user behavior analytics, security information and event management, and encryption can help organizations improve cybersecurity during the COVID-19 pandemic with more remote work.
Data security risks are on the rise in the digitized world we live in. Traditional perimeter security is not enough to protect your critical business data against the risk of data loss.

Attacks
An attack is the deliberate act that exploits
vulnerability
It is accomplished by a threat-agent to
damage or steal an organization’s
information or physical asset
– An exploit is a technique to compromise a system
– A vulnerability is an identified weakness of a
controlled system whose controls are not present
or are no longer effective
– An attack is then the use of an exploit to achieve
the compromise of a controlled system

Editor's Notes
Upon completion of this lesson the student should be able to:
Explain the business need for information security
Describe the threats posed to information security and discuss the more common attacks associated with those threats
Differentiate threats to information systems from attacks against information systems
INTRODUCTION
Information security is unlike any other aspect of information technology. It is an arena where the primary mission is to ensure things stay the way they are.
If there were no threats to information and systems, we could focus on improving systems that support the information, resulting in vast improvements in ease of use and usefulness.
The first phase, Investigation, provides an overview of the environment in which security must operate, and the problems that security must address.
BUSINESS NEEDS FIRST, TECHNOLOGY NEEDS LAST
Information security performs four important functions for an organization:
1.Protects the organization’s ability to function
2.Enables the safe operation of applications implemented on the organization’s IT systems
3.Protects the data the organization collects and uses
4.Safeguards the technology assets in use at the organization
Protecting the Ability of the Organization to Function
Both general management and IR management are responsible for implementing information security to protect the ability of the organization to function.
“information security is a management issue in addition to a technical issue, it is a people issue in addition to the technical issue.”
To assist management in addressing the needs for information security, communities of interest must communicate in terms of business impact and the cost of business interruption and avoid arguments expressed only in technical terms.
Enabling The Safe Operation of Applications
Today’s organizations are under immense pressure to create and operate integrated, efficient, and capable applications.
The modern organization needs to create an environment that safeguards applications using the organization’s IT systems, particularly the environment of the organization’s infrastructure.
Once the infrastructure is in place, management must understand it has not abdicated to the IT department its responsibility to make choices and enforce decisions, but must continue to oversee the infrastructure.
Protecting Data Organizations Collect and Use
Many organizations realize that one of their most valuable assets is their data, because without data, an organization loses its record of transactions and/or its ability to deliver value to its customers.
Protecting data in motion and data at rest are both critical aspects of information security.
An effective information security program is essential to the protection of the integrity and value of the organization’s data.
Safeguarding The Technology Assets in Organizations
To perform effectively, organizations must add secure infrastructure services based on the size and scope of the enterprise.
When an organization grows and more capabilities are needed, additional security services may have to be provided locally.
Likewise, as the organization’s network grows to accommodate changing needs, more robust technology solutions may be needed to replace security programs the organization has outgrown.
THREATS TO INFORMATION SECURITY
To make sound decisions about information security, create policies, and enforce them, management must be informed of the various kinds of threats facing the organization, its applications, data and information systems.
A threat is an object, person, or other entity that represents a constant danger to an asset.
To better understand the numerous threats facing the organization, a categorization scheme has been developed allowing us to group threats by their respective activities.
By examining each threat category in turn, management can most effectively protect its information through policy, education and training, and technology controls.
THREATS TO INFORMATION SECURITY
The 2002 Computer Security Institute/Federal Bureau of Investigation (CSI/FBI) survey on Computer Crime and Security Survey found:
90% of organizations responding, primarily large corporations and government agencies, detected computer security breaches within the last year.
80% of these organizations lost money to computer breaches, totaling over $455,848,000 up from $377,828,700 reported in 2001.
The number of attacks that came across the Internet rose from 70% in 2001 to 74% in 2002.
Only 34% of organizations reported their attacks to law enforcement.

11.Technical Software Failures or Errors
12.Technological Obsolescence
Potential Acts of Human Error or Failure
This category includes the possibility of acts performed without intent or malicious purpose by an individual who is an employee of an organization.
Inexperience, improper training, the making of incorrect assumptions, and other circumstances can cause problems.
Employees constitute one of the greatest threats to information security, as the individuals closest to the organizational data.
Potential Acts of Human Error or Failure
Employee mistakes can easily lead to the following: revelation of classified data, entry of erroneous data, accidental deletion or modification of data, storage of data in unprotected areas, and failure to protect information.
Many threats can be prevented with controls, ranging from simple procedures, such as requiring the user to type a critical command twice, to more complex procedures, such as the verification of commands by a second party.
Potential Deviations in Quality of Service by Service Providers
This category represents situations in which a product or services are not delivered to the organization as expected.
The organization’s information system depends on the successful operation of many inter-dependent support systems including, power grids, telecom networks, parts suppliers, service vendors, and even the janitorial staff and garbage haulers.
Internet service, communications, and power irregularities are three sets of service issues that dramatically affect the availability of information and systems.
Internet Service Issues
For organizations that rely heavily on the Internet and the Web to support continued operations, the threat of the potential loss of Internet service can lead to considerable loss in the availability of information.
Many organizations have sales staff and telecommuters working at remote locations.
When an organization places its web servers in the care of a Web Hosting provider, that outsourcer assumes responsibility for all Internet Services as well as for the hardware and operating system software used to operate the web site.
Communications and other Service Provider Issues
Other utility services can impact organizations as well.
Among these are telephone, water, wastewater, trash pickup, cable television, natural, or propane gas, and custodial services.
The threat of loss of these services can lead to the inability of an organization to function properly.
Power Irregularities
The threat of irregularities from power utilities are common and can lead to fluctuations such as power excesses, power shortages, and power losses.
In the U.S., buildings are “fed” 120-volt, 60-cycle power usually through 15 and 20 amp circuits.
Voltage levels can:
spike – momentary increase or surge – prolonged increase;
sag – momentary low voltage, or brownout – prolonged drop;
fault – momentary loss of power, or blackout – prolonged loss;
Since sensitive electronic equipment, especially networking equipment, computers, and computer-based systems are susceptible to fluctuations, controls can be applied to manage power quality.
Deliberate Acts of Espionage or Trespass
This threat represents a well-known and broad category of electronic and human activities that breach the confidentiality of information.
When an unauthorized individual gains access to the information an organization is trying to protect, that act is categorized as a deliberate act of espionage or trespass.
When information gatherers employ techniques that cross the threshold of what is legal and/or ethical, they enter the world of industrial espionage.
Instances of shoulder surfing occur at computer terminals, desks, ATM machines, public phones, or other places where a person is accessing confidential information.
Deliberate Acts of Espionage or Trespass
The threat of Trespass can lead to unauthorized, real or virtual actions that enable information gatherers to enter premises or systems they have not been authorized to enter.
Controls are sometimes implemented to mark the boundaries of an organization’s virtual territory.
These boundaries give notice to trespassers that they are encroaching on the organization’s cyberspace.
The classic perpetrator of deliberate acts of espionage or trespass is the hacker.
In the gritty world of reality, a hacker uses skill, guile, or fraud to attempt to bypass the controls placed around information that is the property of someone else. The hacker frequently spends long hours examining the types and structures of the targeted systems.
Hackers
There are generally two skill levels among hackers.
The first is the expert hacker, who develops software scripts and codes exploits used by the second category, the novice, or unskilled hacker.
The expert hacker is usually a master of several programming languages, networking protocols, and operating systems and also exhibits a mastery of the technical environment of the chosen targeted system.
However, expert hackers have now become bored with directly attacking systems, and have turned to writing software.
The software they are writing is automated exploits that allow novice hackers to become script kiddies, hackers of limited skill who use expert-written software to exploit a system, but do not fully understand or appreciate the systems they hack.
As a result of preparation and continued vigilance, attacks conducted by scripts are usually predictable, and can be adequately defended against.
Hackers/Crackers
There are other terms for system rule breakers :
The term cracker is now commonly associated with an individual who “cracks” or removes the software protection from an application designed to prevent unauthorized duplication.
A phreaker hacks the public telephone network to make free calls, disrupt services, and generally wreak havoc.
Deliberate Acts of Information Extortion
The threat of information extortion is the possibility of an attacker or formerly trusted insider stealing information from a computer system and demanding compensation for its return or for an agreement to not disclose the information.
Extortion is common in credit card number theft.
Deliberate Acts of Sabotage or Vandalism
Equally popular today is the assault on the electronic face of an organization, its Web site.
This category of threat addresses the individual or group of individuals who want to deliberately sabotage the operations of a computer system or business, or perform acts of vandalism to either destroy an asset or damage the image of the organization.
These threats can range from petty vandalism by employees to organized sabotage against an organization.
Organizations frequently rely on image to support the generation of revenue, so if an organization’s Web site is defaced, a drop in consumer confidence is probable, reducing the organization’s sales and net worth.
Compared to Website defacement, vandalism within a network is more malicious in intent and less public.
Today, security experts are noticing a rise in another form of online vandalism in what are described as hacktivist or cyber-activist operations. A more extreme version is referred to as cyber-terrorism.
Deliberate Acts of Theft
Theft is the illegal taking of another’s property. Within an organization, that property can be physical, electronic, or intellectual.
The value of information suffers when it is copied and taken away without the owner’s knowledge.
Physical theft can be controlled quite easily. A wide variety of measures can be used from simple locked doors, to trained security personnel, and the installation of alarm systems.
Electronic theft, however, is a more complex problem to manage and control. Organizations may not even know it has occurred.
Deliberate Software Attacks
Deliberate software attacks occur when an individual or group designs software to attack an unsuspecting system. Most of this software is referred to as malicious code or malicious software, or sometimes malware.
These software components or programs are designed to damage, destroy, or deny service to the target systems.
Some of the more common instances of malicious code are viruses and worms, Trojan horses, logic-bombs, back doors, and denial-of-services attacks.
Computer viruses are segments of code that perform malicious actions.
This code behaves very much like a virus pathogen attacking animals and plants, using the cell’s own replication machinery to propagate and attack.
The code attaches itself to the existing program and takes control of that program’s access to the targeted computer.
The virus-controlled target program then carries out the virus’s plan, by replicating itself into additional targeted systems.
The macro virus is embedded in the automatically executing macro code, common in office productivity software like word processors, spread sheets, and database applications.
The boot virus, infects the key operating systems files located in a computer’s boot sector.
Worms - malicious programs that replicate themselves constantly without requiring another program to provide a safe environment for replication. Worms can continue replicating themselves until they completely fill available resources, such as memory, hard drive space, and network bandwidth.
Trojan horses - software programs that hide their true nature, and reveal their designed behavior only when activated. Trojan horses are frequently disguised as helpful, interesting or necessary pieces of software, such as readme.exe files often included with shareware or freeware packages.
Back door or Trap door - A virus or worm can have a payload that installs a back door or trap door component in a system. This allows the attacker to access the system at will with special privileges.
Polymorphism - A threat that changes its apparent shape over time, representing a new threat not detectable by techniques that are looking for a pre-configured signature. These threats actually evolve variations in size and appearance to elude detection by anti-virus software programs, making detection more of a challenge.
Virus and Worm Hoaxes - As frustrating as viruses and worms are, perhaps more time and money is spent on resolving virus hoaxes. Well-meaning people spread the viruses and worms when they send e-mails warning of fictitious or virus laden threats.
Compromise of Intellectual Property
Many organizations create or support the development of intellectual property as part of their business operations.
Intellectual property is defined as “the ownership of ideas and control over the tangible or virtual representation of those ideas.”
Intellectual property for an organization includes trade secrets, copyrights, trademarks, and patents.
Once intellectual property (IP) has been defined, and properly identified, breaches to IP constitute a threat to the security of this information.
Most common in IP breaches involve the unlawful use or duplication of software-based intellectual property, known as software piracy.
In addition to the laws surrounding software piracy, two watchdog organizations investigate allegations of software abuse: Software & Information Industry Association (SIIA) formerly the Software Publishers Association, and the Business Software Alliance (BSA).
Enforcement of copyright violations, piracy, and the like has been attempted through a number of technical security mechanisms, including digital watermarks, embedded codes.

Forces of Nature
Forces of nature, force majeure, or acts of God pose the most dangerous threats, because they are unexpected and can occur with very little warning.
These threats can disrupt not only the lives of individuals, but also the storage, transmission, and use of information.
Forces of Nature
These include fire, flood, earthquake, and lightning as well as volcanic eruption and insect infestation.
Since it is not possible to avoid many of these threats, management must implement controls to limit damage and also prepare contingency plans for continued operations.
Technical Hardware Failures or Errors
Technical hardware failures or errors occur when a manufacturer distributes to users equipment containing a known or unknown flaw.
These defects can cause the system to perform outside of expected parameters, resulting in unreliable service or lack of availability.
Some errors are terminal, in that they result in the unrecoverable loss of the equipment. Some errors are intermittent, in that they only periodically manifest themselves, resulting in faults that are not easily repeated.
Technical Software Failures or Errors
This category of threats comes from purchasing software with unknown, hidden faults.
Large quantities of computer code are written, debugged, published, and sold only to determine that not all bugs were resolved.
Sometimes, unique combinations of certain software and hardware reveal new bugs.
Sometimes, these items aren’t errors, but are purposeful shortcuts left by programmers for honest or dishonest reasons.
Technological Obsolescence
When the infrastructure becomes antiquated or outdated, it leads to unreliable and untrustworthy systems.
Management must recognize that when technology becomes outdated, there is a risk of loss of data integrity to threats and attacks.
Ideally, proper planning by management should prevent the risks from technology obsolesce, but when obsolescence is identified, management must take immediate action.
ATTACKS
An attack is the deliberate act that exploits vulnerability.
It is accomplished by a threat-agent to damage or steal an organization’s information or physical asset.
An exploit is a technique to compromise a system. Vulnerability is an identified weakness of a controlled system whose controls are not present or are no longer effective. An attack is then the use of an exploit to achieve the compromise of a controlled system.
Malicious Code
This kind of attack includes the execution of viruses, worms, Trojan horses, and active web scripts with the intent to destroy or steal information.
The state of the art in attacking systems in 2002 is the multi-vector worm.
These attack programs use up to six known attack vectors to exploit a variety of vulnerabilities in commonly found information system devices.
