6 1 Introduction As organisations continue to move business online, valuable corporate and financial assets are now connected to the Internet with application interfaces, exposing firms to sophisticated attacks. With the pervasiveness of critical Web applications, threats are increasingly bypassing traditional firewall security controls resulting in the majority of attack traffic now using the HTTP protocol to target Web applications. The severity of such attacks is underscored by the findings from Web Application Security Consortium (WASC) which estimates that more than 95% of Web applications today have one or more vulnerabilities. The security threats are not only increasing in number but also in sophistication. As applications migrate to the Web, they can be accessed and potentially exploited from anywhere in the world. Web applications (Layer seven of OSI model) are fast becoming an attractive target for hackers. Layer seven attacks have grown year over year and now make up for 62% of all cyber-attacks according to Symantec. The frequency and number of attacks is constantly on the rise and Web applications can be targeted from any geographic location around the world. 1.1 Service summary Web Application Firewall is provided by Atos powered by Akamai delivering a managed service that provides customers the ability to detect potential web application attacks in HTTP traffic as it passes through the Akamai infrastructure before the traffic reaches customer s data centre. The service can be configured such that once anomalous and potentially malicious patterns in HTTP request headers are detected an alert can be issued or the traffic blocked altogether. Important characteristics: Risk Mitigation PCI DSS 6.6 1

7 2 Service overview How the Web Application Firewall service works Web Application Firewall is a distributed WAF that provides a highly scalable, outer defensive ring for Web application protection. The module, through the implementation of network and Application Layer controls, helps prevent threats and exploitation techniques such as SQL Injection, Cross Site Scripting (XSS) and other HTTP attacks. The Application Layer control detects and prevents application-layer attacks using a pre-defined core rule set based on ModSecurity, a trusted and proven industrystandard rule set that provides security against major exploitation techniques including Cross Site Scripting, SQL Injection, and other common application layer threats that target the customer s origin servers and associated applications. The module allows changes to firewall rules to customize the defence perimeter for each specific environment being protected. WAF is an embedded process within the Akamai Edge Platform. As such, it is capable of inspecting both HTTP and HTTPS requests before either serving the request. Because Akamai holds a private key used for encrypting SSL between the client and the Edge platform, customers who accelerate their secure application using Secure Delivery or Web Application Accelerator can easily enable WAF to protect these applications as well all without the problem of having to share a private key with Akamai. Portal Based Configuration WAF is fully managed through the EdgeControl portal. Customers select, configure, enable and disable pre-defined firewall rules via the EdgeControl portal. For rules that are enabled, multiple actions are available such as alert only, drop, and notify. Changes to firewall policies can be implemented using a Fast Channel to propagate updates across the global Akamai network within several hours. The Application Layer control is designed to detect and prevent Application Layer attacks targeting the customer s origin servers and associated applications. WAF through the implementation of network and Application Layer controls helps mitigate application threats and exploitation techniques such as SQL Injection, Cross Site Scripting (XSS) and other HTTP attacks. Application Layer Controls WAF provides customers a rich set of Application Layer protocol rules that mitigate the risks associated with many of their Web application vulnerabilities. Customers can enable a default set of rules that are designed to protect against attacks described in the OWASP top 10. Provides protection against common Web layer attacks such as Cross Site Scripting, SQL Injection, HTTP Response Splitting, and Command Injection. Individual rules can be enabled / disabled and can be configured to block or alert. Network Layer Controls The WAF service also provides network layer controls to allow or restrict requests from certain IP addresses to protect the origin server from application layer attacks. 2

8 IP Black List The ability to define through a web portal, a list of IP addresses/cidr blocks to be blocked along with the subnet masks to be used in the matching process; the list can be up to 512 entries. IP address updates can be propagated within 30 minutes. This supports a negative security model of accept all except that which is explicitly denied. IP White List The ability to define through a web portal, a list of IP addresses, or IP address ranges to be allowed; the individual IP address list can be up to 512 entries; IP address updates can be propagated within 30 minutes. The IP White List is used in conjunction with the Strict Whitelist feature, which allows traffic only from the defined addresses, while denying all other traffic. Strict IP White List Allows only those IPs in the allowed IPs list, all other IPs are denied. This supports a positive security model of deny all except that which is explicitly trusted Rate Control This Web Application Firewall feature enables a customer to specify the number of requests per second against a given URL, monitoring and controlling the rate of requests against the Akamai EdgePlatform. Rate Categories can be incorporated as WAF rules thus enabling the customer to dynamically alert and/or block client exhibiting excessive request rate behaviours. If a client IP exhibits a request rate that exceeds either the Burst Threshold or the Average Threshold, their requests can be controlled until their associated request rate decreases to acceptable values. Custom Rules This feature enables a user to create Web Application Firewall rules. Custom rules enable the Web Application Firewall to customize the application layer defence stance and can serve as Virtual Patches wherein new website vulnerabilities may be mitigated quickly by the WAF while the application is patched and redeployed over time. Like all WAF features the propagation of Custom Rules configurations is done via the WAF FastChannel. Additionally, the actions of each custom rule will be reported alongside that of standard rules. Logging and Reporting The Web Application Firewall makes event logging and auditing, reporting and compliance checks available through the EdgeControl portal. Logging The Web Application Firewall supports event logging. Customers can elect to log firewall events using the log delivery service (LDS), which now supports the addition of WAF events in the W3C and combined formats. Alternatively, customers can employ the new Real Time Reporting functionality that enables customers to incorporate WAF firewall events in near real time into their log management or security information and event management (SIEM) infrastructures. This new feature enables customers to increase their threat posture awareness. Reporting Reports such as the Firewall Rule Activities and Blocked IP s are constantly updated and delivered via the EdgeControl Portal. 3

9 3 Information assurance Web Application Firewall is appropriate for processing IL0 data. 4

10 4 Backup/restore and disaster recovery The Akamai platform offers 100% availability and is designed to withstand multiple points of failure. The platform is fully resilient and allows for multiple versions of a customer configuration to be kept. Customers are able to create a new configuration and push it out to testing and then production, or revert to a previous configuration all through the customer portal. 5

11 5 On-boarding and off-boarding The Atos Web Application Firewall service requires professional services to scope and integrate the applications to be protected. As such the on-boarding process is customised and defined through this initial professional services. A typical on-boarding process will involve the following stages: Scoping and gating to gather the necessary details for the site. Identify any potential issues with site integration or additional features that may need to be enabled Resourcing to identify and allocate resources to best fit the integration requirements and timescales. Additional discovery of the environment to a more detailed level. This is carried out by professional services in conjunction with the customer and builds on this initial gating Internal testing or pre-configuration to ensure any unusual requirements or environments are tested before an initial customer configuration Initial Configuration Creation of a suitable configuration for the site delivery service and perform internal testing Staging, once tested, the configuration is pushed to a staging environment to allow the customer access to start initial testing Staged Testing, working with the customer to address any issues in the configuration identified during the testing. 6

13 7 Service management Atos Service Management Model (ASMM) The Atos Service Management Model (ASMM) is a set of service management processes implemented in the Atos organization by which Atos controls the delivery of continuous IT support services (services that a client buys on a longterm basis) and aligns these services to the customer s needs. As a major player in the provision of continuous IT services to the world s premier league companies, we act in a globally consistent manner, presenting a common interface to the client 24 hours a day, 7 days a week. ASMM is built on the best practices in the ICT industry, as defined in the ITIL library version 3 (2011), enriched by the Service Delivery Best Practices of the former Atos Origin and Siemens Information Services. ASMM underpins both ISO/IEC (previously BS15000), the International Service Management Standard for IT service management and ISO/IEC 27001: Information technology -- Security techniques -- Information security management systems Requirements. Special attention is given to the end-to-end governance of the services cross the delivery units within Atos (on-, near or offshore), demand supply alignment and immediate communication of major service disruptions (incidents) and major changes to the clients demand organization and involving them in priority setting and resolution progress.

25 18 Abbreviations and definitions Abbreviation / term: Adaptive Caching Cross Site Scripting (XSS) Denial of Service (DoS) Attack & Distributed Denial of Service (DDoS) Attack HTTP (S) HTTP POST ISO20000 ISO27001 Version A feature where customer identified content is served from the Edge during an attack, maintaining service where the originating servers(s) may be affected. Cross-site scripting (XSS) is a type of computer security vulnerability typically found in Web applications. XSS enables attackers to inject client-side script into Web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same origin policy Denial-of-Service attack (DoS attack) or Distributed Denial-of-Service attack (DDoS attack) is an attempt to make a machine or network resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of efforts to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet. A distributed attack includes multiple attack sources. Hyper Text Transfer Protocol (Secure):-Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text and is the basis of the World Wide Web (www). HTTP is the protocol to exchange or transfer hypertext. HTTP utilises port 80, while HTTPS uses port 443 and utilises security mechanisms in the transmission of the data. A function of the HTTP protocol allowing information to be sent to a web service such as a block of data that is the result of submitting a web form to a data-handling process; or an item to add to a database. ISO/IEC is the first international standard for IT service management. It was developed in 2005, by ISO/IEC JTC1 SC7 and revised in 2011.[1] It is based on and intended to supersede the earlier BS ISO/IEC 27001:2005, part of the growing ISO/IEC family of standards, is an information security management system (ISMS) standard published in October 2005 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

Mega Bytes a measure of cumulative network traffic Mega bits per second a measure of network bandwidth / throughput Million page views The Open Systems Interconnection (OSI) model (ISO/IEC ) is a conceptual model that groups similar communication functions into one of seven logical layers. A layer serves the layer above it and is served by the layer below it. For example, a layer that provides errorfree communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that make up the contents of that path. The Open Web Application Security Project (OWASP) is an open-source web application security project. The OWASP community includes corporations, educational organizations, and individuals from around the world. This community works to create freely-available articles, methodologies, documentation, tools, and technologies. The Payment Card Industry Data Security Standard (PCI DSS) is a proprietary information security standard for organizations that handle cardholder information for the major debit, credit, prepaid, e-purse, ATM, and POS cards. SQL injection is a code injection technique, used to attack data driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker). Techniques used as part of DoS or DDos attacks.

27 Abbreviation / term: Web Application Firewall Version A web application firewall is a form of firewall which controls input, output, and/or access from, to, or by a web application or service. It operates by monitoring and potentially blocking the input, output, or system service calls which do not meet the configured policy of the firewall. The application firewall is typically built to control all network traffic on any OSI layer up to the application layer. It is able to control applications or services specifically, unlike a stateful network firewall which is - without additional software - unable to control network traffic regarding a specific application. 22
