While a business continuity plan (BCP) takes a broad approach to dealing with organizational-wide effects of a disaster, a disaster recovery plan (DRP), which is a subset of the business continuity plan, is instead focused on taking the necessary steps to resume normal business operations as quickly as possible. A disaster recovery plan is executed immediately after the disaster occurs and details what steps are to be taken in order to recover critical information technology infrastructure.

 

Laws and regulations

Below is a partial listing of European, United Kingdom, Canadian and USA governmental laws and regulations that have, or will have, a significant effect on data processing and information security. Important industry sector regulations have also been included when they have a significant impact on information security.

UK Data Protection Act 1998 makes new provisions for the regulation of the processing of information relating to individuals, including the obtaining, holding, use or disclosure of such information. The European Union Data Protection Directive (EUDPD) requires that all EU member must adopt national regulations to standardize the protection of data privacy for citizens throughout the EU.

The Computer Misuse Act 1990 is an Act of the UK Parliament making computer crime (e.g. cracking - sometimes incorrectly referred to as hacking) a criminal offence. The Act has become a model upon which several other countries including Canada and the Republic of Ireland have drawn inspiration when subsequently drafting their own information security laws.

EU Data Retention laws requires Internet service providers and phone companies to keep data on every electronic message sent and phone call made for between six months and two years.

The Family Educational Rights and Privacy Act (FERPA) (20 U.S.C. § 1232 g; 34 CFR Part 99) is a USA Federal law that protects the privacy of student education records. The law applies to all schools that receive funds under an applicable program of the U.S. Department of Education. Generally, schools must have written permission from the parent or eligible student in order to release any information from a student's education record.

Health Insurance Portability and Accountability Act (HIPAA) of 1996 requires the adoption of national standards for electronic health care transactions and national identifiers for providers, health insurance plans, and employers. And, it requires health care providers, insurance providers and employers to safeguard the security and privacy of health data.

Gramm-Leach-Bliley Act of 1999 (GLBA), also known as the Financial Services Modernization Act of 1999, protects the privacy and security of private financial information that financial institutions collect, hold, and process.

Sarbanes-Oxley Act of 2002 (SOX). Section 404 of the act requires publicly traded companies to assess the effectiveness of their internal controls for financial reporting in annual reports they submit at the end of each fiscal year. Chief information officers are responsible for the security, accuracy and the reliability of the systems that manage and report the financial data. The act also requires publicly traded companies to engage independent auditors who must attest to, and report on, the validity of their assessments.

Payment Card Industry Data Security Standard (PCI DSS) establishes comprehensive requirements for enhancing payment account data security. It was developed by the founding payment brands of the PCI Security Standards Council, including American Express, Discover Financial Services, JCB, MasterCard Worldwide and Visa International, to help facilitate the broad adoption of consistent data security measures on a global basis. The PCI DSS is a multifaceted security standard that includes requirements for security management, policies, procedures, network architecture, software design and other critical protective measures.

State Security Breach Notification Laws (California and many others) require businesses, nonprofits, and state institutions to notify consumers when unencrypted "personal information" may have been compromised, lost, or stolen.

Personal Information Protection and Electronics Document Act (PIPEDA) – An Act to support and promote electronic commerce by protecting personal information that is collected, used or disclosed in certain circumstances, by providing for the use of electronic means to communicate or record information or transactions and by amending the Canada Evidence Act, the Statutory Instruments Act and the Statute Revision Act.

 

 

Sources of standards

International Organization for Standardization (ISO) is a consortium of national standards institutes from 157 countries, coordinated through a secretariat in Geneva, Switzerland. ISO is the world's largest developer of standards. ISO 15443: "Information technology - Security techniques - A framework for IT security assurance", ISO/IEC 27002: "Information technology - Security techniques - Code of practice for information security management", ISO-20000: "Information technology - Service management", and ISO/IEC27001: "Information technology - Security techniques - Information security management systems - Requirements" are of particular interest to information security professionals.

 

The USA National Institute of Standards and Technology (NIST) is a non-regulatory federal agency within the U.S. Department of Commerce. The NIST Computer Security Division develops standards, metrics, tests and validation programs as well as publishes standards and guidelines to increase secure IT planning, implementation, management and operation. NIST is also the custodian of the USA Federal Information Processing Standard publications (FIPS).

 

The Internet Society is a professional membership society with more than 100 organization and over 20,000 individual members in over 180 countries. It provides leadership in addressing issues that confront the future of the Internet, and is the organization home for the groups responsible for Internet infrastructure standards, including the Internet Engineering Task Force (IETF) and the Internet Architecture Board (IAB). The ISOC hosts the Requests for Comments (RFCs) which includes the Official Internet Protocol Standards and the RFC-2196 Site Security Handbook.

The Information Security Forum is a global nonprofit organization of several hundred leading organizations in financial services, manufacturing, telecommunications, consumer goods, government, and other areas. It undertakes research into information security practices and offers advice in its biannual Standard of Good Practice and more detailed advisories for members.

 

The IT Baseline Protection Catalogs, or IT-Grundschutz Catalogs, ("IT Baseline Protection Manual" before 2005) are a collection of documents from the German Federal Office for Security in Information Technology (FSI), useful for detecting and combating security-relevant weak points in the IT environment (IT cluster). The collection encompasses over 3000 pages with the introduction and catalogs.

 

User account policy

User Account Policy is a document which outlines the requirements for requesting and maintaining an account on computer systems or networks, typically within an organization. It is very important for large sites where users typically have accounts on many systems. Some sites have users read and sign an Account Policy as part of the account request process.Contents  [hide]

Policy Content

  • Should state who has the authority to approve account requests.
  • Should state who is allowed to use the resources (e.g., employees or students only)
  • Should state any citizenship/resident requirements.
  • Should state if users are allowed to share accounts or if users are allowed to have multiple accounts on a single host.
  • Should state the users’ rights and responsibilities.
  • Should state when the account should be disabled and archived.
  • Should state how long the account can remain inactive before it is disabled.
  • Should state password construction and aging rules.

 

 

 

 

Remote access policy

Remote access policy is a document which outlines and defines acceptable methods of remotely connecting to the internal network. It is essential in large organization where networks are geographically dispersed and extend into insecure network locations such as public networks or unmanaged home networks. It should cover all available methods to remotely access internal resources:

  • dial-in (SLIP, PPP)
  • ISDN/Frame Relay
  • telnet access from Internet
  • Cable modem

 

This remote access policy defines standards for connecting to the organizational network and security standards for computers that are allowed to connect to the organizational network.

This remote access policy specifies how remote users can connect to the main organizational network and the requirements for each of their systems before they are allowed to connect.

 

Internet security

Internet security is a branch of computer security[1] specifically related to the Internet. Its objective is to establish rules and measures to use against attacks over the Internet.[2] The Internet represents an insecure channel for exchanging information leading to a high risk of intrusion or fraud, such as phishing.[3] Different methods have been used to protect the transfer of data, including encryption.

 

 

 

 

Types of security

Network layer security

TCP/IP can be made secure with the help of cryptographic methods and protocols that have been developed for securing communications on the Internet. These protocols include SSL and TLS for web traffic, PGP for email, and IPsec for the network layer security.

 

IPsec Protocol

This protocol is designed to protect communication in a secure manner using TCP/IP. It is a set of security extensions developed by IETF, and it provides security and authentication at the IP layer by using cryptography. To protect the content, the data is transformed using encryption techniques. There are two main types of transformation that form the basis of IPsec: the Authentication Header (AH) and Encapsulating Security Payload (ESP). These two protocols provide data integrity, data origin authentication, and anti-replay service. These protocols can be used alone or in combination to provide the desired set of security services for the Internet Protocol (IP) layer.

 

The basic components of the IPsec security architecture are described in terms of the following functionalities:

  • Security protocols for AH and ESP
  • Security association for policy management and traffic processing
  • Manual and automatic key management for the internet key exchange (IKE)
  • Algorithms for authentication and encryption

 

The set of security services provided at the IP layer includes access control, data origin integrity, protection against replays, and confidentiality. The algorithm allows these sets to work independently without affecting other parts of the implementation. The IPsec implementation is operated in a host or security gateway environment giving protection to IP traffic.

 

Electronic mail security (E-mail)

Background

Email messages are composed, delivered, and stored in a multiple step process, which starts with the message's composition. When the user finishes composing the message and sends it, the message is transformed into a standard format: an RFC 2822 formatted message. Afterwards, the message can be transmitted. Using a network connection, the mail client, referred to as a mail user agent (MUA), connects to a mail transfer agent (MTA) operating on the mail server. The mail client then provides the sender’s identity to the server. Next, using the mail server commands, the client sends the recipient list to the mail server. The client then supplies the message. Once the mail server receives and processes the message, several events occur: recipient server identification, connection establishment, and message transmission. Using Domain Name System (DNS) services, the sender’s mail server determines the mail server(s) for the recipient(s). Then, the server opens up a connection(s) to the recipient mail server(s) and sends the message employing a process similar to that used by the originating client, delivering the message to the recipient(s).

 

Pretty Good Privacy (PGP)

PGP provides confidentiality by encrypting messages to be transmitted or data files to be stored using an encryption algorithm such 3DES or CAST-128. Email messages can be protected by using cryptography in various ways, such as the following:

  • Signing an email message to ensure its integrity and confirm the identity of its sender.
  • Encrypting the body of an email message to ensure its confidentiality.
  • Encrypting the communications between mail servers to protect the confidentiality of both the message body and message header.

The first two methods, message signing and message body encryption, are often used together; however, encrypting the transmissions between mail servers is typically used only when two organizations want to protect emails regularly sent between each other. For example, the organizations could establish a virtual private network (VPN) to encrypt the communications between their mail servers over the Internet.[4] Unlike methods that can only encrypt a message body, a VPN can encrypt entire messages, including email header information such as senders, recipients, and subjects. In some cases, organizations may need to protect header information. However, a VPN solution alone cannot provide a message signing mechanism, nor can it provide protection for email messages along the entire route from sender to recipient.

 

Multipurpose Internet Mail Extensions (MIME)

MIME transforms non-ASCII data at the sender's site to Network Virtual Terminal (NVT) ASCII data and delivers it to client's Simple Mail Transfer Protocol (SMTP) to be sent through the Internet.[5] The server SMTP at the receiver's side receives the NVT ASCII data and delivers it to MIME to be transformed back to the original non-ASCII data.

  • Secure/Multipurpose Internet Mail Extensions (S/MIME)

S/MIME provides a consistent means to securely send and receive MIME data. S/MIME is not only limited to email but can be used with any transport mechanism that carries MIME data, such Hypertext Transfer Protocol (HTTP).[6]

 

Message Authentication Code

A Message Authentication Code is a cryptography method that uses a secret key to encrypt a message. This method outputs a MAC value that can be decrypted by the receiver, using the same secret key used by the sender. The Message Authentication Code protects both a message's data integrity as well as its authenticity.

Firewalls

A firewall controls access between networks. It generally consists of gateways and filters which vary from one firewall to another. Firewalls also screen network traffic and are able to block traffic that is dangerous. Firewalls act as the intermediate server between SMTP and HTTP connections.

 

Role of firewalls in Internet security and web security

Firewalls impose restrictions on incoming and outgoing packets to and from private networks. All the traffic, whether incoming or outgoing, must pass through the firewall; only authorized traffic is allowed to pass through it. Firewalls create checkpoints between an internal private network and the public Internet, also known as choke points. Firewalls can create choke points based on IP source and TCP port number. They can also serve as the platform for IPsec. Using tunnel mode capability, firewall can be used to implement VPNs. Firewalls can also limit network exposure by hiding the internal network system and information from the public Internet.

 

Types of firewalls

Packet filters

Packet filters are one of several different types of firewalls that process network traffic on a packet-by-packet basis. Their main job is to filter traffic from a remote IP host, so a router is needed to connect the internal network to the Internet. The router is known as a screening router, which screens packets leaving and entering the network.

 

 

 

Circuit-level gateways

The circuit-level gateway is a proxy server that statically defines what traffic will be allowed. Circuit proxies always forward packets containing a given port number, provided the port number is permitted by the rules set. This gateway operates at the network level of an OSI model. The main advantage of a proxy server is its ability to provide Network Address Translation (NAT), which can hide the user's IP address from the Internet, effectively protecting all internal information from the Internet.

 

Application-level gateways

An application-level gateway is a proxy server operating at the TCP/IP application level. A packet is forwarded only if a connection is established using a known protocol. Application-level gateways are notable for analyzing entire messages rather than individual packets of data when the data are being sent or received.

 

Malicious software and antivirus

Malware

Commonly, a computer user can be tricked or forced into downloading software onto a computer that is of malicious intent. Such programs are known as malware and come in many forms, such as viruses, Trojan horses, spyware, and worms. Malicious software is sometimes used to form botnets.

Viruses

Viruses are programs that can replicate their structures or effects by infecting other files or structures on a computer. The common use of a virus is to take over a computer to steal data.

Trojan horse

A Trojan horse (commonly known as a Trojan) is a general term for malicious software that pretends to be harmless so that a user willingly allows it to be downloaded onto the computer.

Spyware

The term spyware refers to programs that surreptitiously monitor activity on a computer system and report that information to others without the user's consent.

Worms

Worms are programs that can replicate themselves throughout a computer network, performing malicious tasks throughout.

Botnet

A botnet is a network of "zombie" computers that have been taken over by a "bot" that performs large-scale malicious acts for the creator of the botnet.

Antivirus

Antivirus programs and Internet security programs are useful in protecting a computer or programmable device from malware.

Such programs are used to detect and usually eliminate viruses; however, it is now common to see security suites, containing also firewalls, anti-spyware, theft protection, and so on to more thoroughly protect users.[8]

Traditionally, a user would pay for antivirus software; however, computer users now can, and do, download from a host of free security applications on the Internet.

Industrial espionage

Industrial espionage, economic espionage or corporate espionage is a form of espionage conducted for commercial purposes instead of purely national security purposes. Economic espionage is conducted or orchestrated by governments and is international in scope, while industrial or corporate espionage is more often national and occurs between companies or corporations.

Competitive intelligence and economic or industrial espionage

'Competitive intelligence' describes the legal and ethical activity of systematically gathering, analyzing and managing information on industrial competitors.It may include activities such as examining newspaper articles, corporate publications, websites, patent filings, specialised databases, information at trade shows and the like to determine information on a corporation. The compilation of these crucial elements is sometimes termed CIS or CRS, a Competitive Intelligence Solution or Competitive Response Solution. With its roots in market research, 'competitive intelligence' has been described as the 'application of principles and practices from military and national intelligence to the domain of global business'; it is the business equivalent of open-source intelligence.

 

In theory, the difference between 'competitive intelligence' and economic or industrial espionage is clear. In practice, it is sometimes quite difficult to tell the difference between legal and illegal methods. Especially if one starts to consider the ethical side of information gathering, the border becomes even more blurred and elusive of definition.

 

Forms of economic and industrial espionage

Economic or industrial espionage takes place in two main forms. In short, the purpose of espionage is to gather knowledge about (an) organization(s). It may include the acquisition of intellectual property, such as information on industrial manufacture, ideas, techniques and processes, recipes and formulas. Or it could include sequestration of proprietary or operational information, such as that on customer datasets, pricing, sales, marketing, research and development, policies, prospective bids, planning or marketing strategies or the changing compositions and locations of production.[2] It may describe activities such as theft of trade secrets, bribery, blackmail and technological surveillance. As well as orchestrating espionage on commercial organizations, governments can also be targets —for example, to determine the terms of a tender for a government contract so that another tenderer can underbid.

Target industries

Economic and industrial espionage is most commonly associated with technology-heavy industries, including computer software and hardware, biotechnology, aerospace, telecommunications, transportation and engine technology, automobiles, machine tools, energy, materials and coatings and so on. Silicon Valley is known to be one of the world's most targeted areas for espionage, though any industry with information of use to competitors may be a target.

 

Information theft and sabotage

Information can make the difference between success and failure; if a trade secret is stolen, the competitive playing field is leveled or even tipped in favor of a competitor. Although a lot of information-gathering is accomplished legally through competitive intelligence, at times corporations feel the best way to get information is to take it. Economic or industrial espionage is a threat to any business whose livelihood depends on information.

 

In recent years, economic or industrial espionage has taken on an expanded definition. For instance, attempts to sabotage a corporation may be considered industrial espionage; in this sense, the term takes on the wider connotations of its parent word. That espionage and sabotage (corporate or otherwise) have become more clearly associated with each other is also demonstrated by a number of profiling studies, some government, some corporate. The US Government currently has a polygraph examination entitled the "Test of Espionage and Sabotage" (TES, contributing to the increasingly popular, though not consensus, notion, by those studying espionage and sabotage countermeasures, of the interrelationship between the two.In practice, particularly by 'trusted insiders,' they are generally considered functionally identical for the purpose of informing countermeasures.
