3 INTRODUCTION Faced with a growing number of regulatory, corporate, and industry requirements, organizations must be absolutely sure their important applications and data are secure when deploying them through a software-as-aservice (SaaS) model. This is as true for IT service management as for any other application. IT service management does the critical work of assuring IT applications, devices, and services are available to meet business needs. Juggling IT service management tasks, such as help desk calls, requests for new servers, required security updates, and changes in user access rights, is difficult enough. Maintaining the hardware, software, and storage required to run the IT service management solution is, for some organizations, not a good use of staff, budget, or time. Choosing a SaaS solution lets organizations reduce their management costs and focus on keeping applications running, passwords updated, servers patched, and employees productive rather than on running the IT service management infrastructure. Yet IT service management applications may hold sensitive data about users and the business, ranging from the names of servers to changes in employee status. With its BMC Remedy OnDemand SaaS offering, BMC has built in the security tools and processes needed to provide the strongest possible protection for data. This means that you can reduce the total cost of ownership of IT service management, while also securing your sensitive corporate and user information. This white paper examines the key security concerns facing organizations considering BMC Remedy OnDemand, and how BMC addresses these concerns. Page 3

4 DATA SECURITY The data contained in IT service management systems ranges from ticket structures to the tickets themselves to usage logs. Organizations must be assured this data is secure, both during the initial migration of IT service management data to the BMC data center and whenever they retrieve that data for reporting or other purposes. BMC maintains the security of the network infrastructure with a three-tiered architecture consisting of an external zone, a DMZ, and an internal zone. All are protected by firewalls and network monitoring devices, as well as by intrusion prevention systems that are monitored 24x7 by a security operations center. (See Figure 1) Figure 1. The BMC Remedy OnDemand three-tiered architecture, with the BMC Remedy system and the data safely in the internal zone i All servers that access or store data are protected by antivirus software and are hardened at the operating system, database, and application levels against attack through a series of defined policies and procedures. Any changes made to the operating system, database, or application configurations are monitored by change management processes to ensure that an accepted baseline is maintained. Security and other patches are Page 4

All data entering the BMC cloud is encrypted using IP SEC or a minimum of AES 256-bit encryption. What s more, BMC can comply with any authentication policies established by your organization for your own employees. (See Figure 2) AES 256-bit encryption Figure2.

6 SECURE BACKUP Sensitive data, such as that stored in IT service management systems, must be protected both at rest in servers and on storage arrays and in transit, such as during backups. Backups that are done within the BMC data center are protected by its firewalls, network, and server protection policies. Backup to a remote location, if requested, is encrypted through a VPN with a minimum of AES 256-bit encryption. Sensitive data must be protected both at rest in servers and on storage arrays and in transit. If you require the use of digital signatures to assure the authenticity of the sending or receiving device, BMC is prepared to adopt any PKI model that you request. ADMINISTRATIVE ACCESS Given that many attacks on corporate data are carried out by insiders, it s critical that you can restrict which users have administrative access to your IT service management system (and thus can see all the tickets in process or even change the look and feel of the system) and which users can see only the tickets that they have submitted. BMC administrators must pass through a two-factor authentication system before accessing servers and network devices through a VPN. By default, all administrators are given the minimum access needed to do their jobs, and are granted greater privileges only as needed. The authentication system logs all transactions and user activity, allowing its use as not only a security tool, but also as a tool for auditing, accounting, and compliance. PATCHING PROCESSES As new vulnerabilities are identified, software vendors respond with patches to remediate them and protect sensitive data. Although regular patches are essential to maintaining security, in a SaaS environment, you must rely on your vendor for that patching. You must also rely on the vendor to test patches to ensure they do not harm applications, and to have processes in place to roll back the patches if needed. As hackers roll out new attacks, applying regular patches is essential to maintaining security. BMC applies all required patches to its BMC Remedy OnDemand environment at least monthly, with critical patches applied as soon as they have been tested and made available. All patches are tested in a staging environment before being released to production to ensure system stability and performance. Page 6

7 SECURITY CERTIFICATIONS Security certifications are a critical indicator of the level of skill and commitment a SaaS provider brings to protecting data. BMC Remedy OnDemand for Public Sector's infrastructure data centers are audited annually to the SAS-70 Type 2/SSAE 16 Type 2 standard and maintain ISO/IEC certification. The latest available audit reports are: 1) SSAE 16, SOC1 Report for Plano Technology Center (PTC); for period of 1/1/2011 through 10/31/2011 2) SSAE 16, SOC1 Report for Florence Technology Center (FTC) ); for period of 1/1/2011 through 10/31/2011 PENETRATION TESTS Periodic penetration tests are essential to assuring that the proper security tools and processes are in place to meet ever-changing security threats. A SaaS vendor should rigorously perform such tests. BMC maintains a third-party white hat security penetration team that regularly conducts tests of the security of its BMC Remedy OnDemand environment. BMC s Web application monitoring teams continually monitor the results of such tests and remediate any vulnerability that is found. (See Figure 3) Page 7

8 Figure 3. BMC employs proper protection from outside attacks to ensure data center is secure i BMC also performs a weekly critical parameters audit and monthly operations review. An outside vendor conducts an external ISO audit and a penetration test every six months as well as annual SSAE 16 Type II and ISAE 3402 Type II audits. DISASTER RECOVERY/BUSINESS CONTINUITY (DR/BC) Being able to quickly resume operations in the wake of a natural or man-made disaster is critical in today s 24x7 economy. When you run your own data centers, you can control the nature, scope, and quality of your DR/BC efforts. However, when deploying applications in a SaaS model, you must get assurances from your SaaS vendor that the proper steps are being taken to assure application uptime. BMC Remedy OnDemand environment uses industry-standard, high-capacity servers and a network infrastructure employing redundant switches and networks to avoid a single point of failure. The use of clustered servers and backup systems helps assure uninterrupted access to service desk functions even in the event of system failure. BMC also follows its own DR/BC policies, which are continuously updated and modified to reflect changes in the technical and business environments, as well as its own regular mock drills and tests. NOTIFICATION OF SECURITY BREACHES Organizations that trust their data to a SaaS provider need to know if the vendor has suffered a security breach, so that they can take the proper steps internally to safeguard their data and to make any legally required notifications. BMC has a formal incident response and reporting procedure that is tested regularly. BMC REMEDY ONDEMAND FOR PUBLIC SECTOR As the first and only cloud-based IT service management solution designed to support the Federal Information Security Management Act (FISMA) with Low and Moderate NIST controls for infrastructure, services, and applications, BMC Remedy OnDemand for Public Sector is managed by U.S. staff from U.S.-based data centers. ENCRYPTION In support of FISMA and FIPS-197, BMC uses one of the strongest block ciphers available, the Advanced Encryption Standard (AES), and encrypts all application and database data at the 256-AES level and with SSL assurance. AES specifies a FIPS-approved cryptographic algorithm that can be used to protect electronic data. The AES algorithm is a symmetric block cipher that can encrypt (encipher) and decrypt (decipher) information. Encryption converts data to an unintelligible form called ciphertext; decrypting the ciphertext converts the data back into its original form, called plaintext. The AES algorithm is capable of using cryptographic keys of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. Encrypting databases at rest is an important part of most regulatory compliance requirements, such as PCI, HIPAA, FISMA, and HiTech, and can help protect all of your agency s sensitive data. U.S.-BASED SOLUTION SUPPORT BMC has implemented its cloud offering in U.S.-based data centers (both primary and recovery sites) that are managed by U.S.-based personnel. Although data is encrypted, as an additional layer of security, BMC employees who may have visibility into customer data are U.S. citizens. Page 8
