1 BY VORAPOJ LOOKMAIPUN CISSP, CISA, CISM, CRISC, CEH Agenda Security Cases What is Cloud? Road Map Security Concerns 1

2 Security Cases on Cloud Data Protection - Two arrested in ipad Security Breach (Jan 2011) - 2 computer hackers gathered 120,000 Apple ipad users addresses and personal information. - Epsilon Breach (April 2011) - Epsilon, marketing company,(for Best Buy, Ethan Allen, Walgreens, Target) hackers compromised 50 clients address, and send out phishing s masquerading the client to their customers. - Data Availability - Hotmail (Jan 2011) - 17,355 customers impacted temporarily lost the mail contents through the course of mailbox load balancing between servers - Amazon EC2 (web hosting) offline (April, 2011) - Foursquare, Reddit and Quora were among the sites went offline. 2

3 Security Cases on Cloud - Denial of Service - Bot herders hid master control Channel in Google cloud (October 2009) - Google s App Engine was tapped to act as the master control channel, by download malicious program to infected PC for making part of botnet. Data breach Gawker news site compromised (Dec 2010) Gawker news site (Gizmodo, Lifehacker, Kotaku, io9 or Jezebel) were stolen 1.3 million passwords and uploaded via torrent file. Microsoft BPOS hacked (Dec 2010) Microsoft Business Productivity Online Suite was accesses and company data was downloaded. BPOS includes Exchange online, SharePoint Online, Office communications Online and Office Live meeting. MS BPOS standard customer could be downloaded by other customers of the service. 3

4 Data breaches are the main concern for business moving to cloud Survey Cloud computing More than 40% respondents report that their organization uses cloud computing 69 % SaaS 47% IaaS 55% PaaS Source: The 2012 Global State of Information Security Survey by pwc 4

5 Survey Cloud computing Has the cloud improved security? 54% Yes 23% Believe the security has weakened 18% No change 5% Don t know Source: The 2012 Global State of Information Security Survey by pwc Survey Cloud computing What about the greatest risks to cloud computing strategies? 32% Uncertain ability to enforce provider site security policies 19% Inadequate training and IT auditing 15% Questionable privileged access control at provider site 11% Proximity of data to someone else s 9% Uncertain ability to recover data Source: The 2012 Global State of Information Security Survey by pwc 5

6 WHAT IS CLOUD? 6

7 Cloud Computing Economies of Scale What is Cloud? NITS SP The NIST Definition of Cloud Computing (2011) A model for enabling, ubiquitous, convenient, on-demand network access to shared pool of configuration computing resources (e.g. networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. 7

8 What is Cloud Computing? Composed of 5 Essential characteristics 3 Service models 4 Deployment models. Essential Characteristics 5 Essential Characteristics 1. On-demand self service 2. Broad network access 3. Resources pooling 4. Rapid elasticity 5. Measured service 8

9 Essential Characteristics 1. On-demand self service A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider เช าเป นช วงเวลา (นาท ) Essential Characteristics 2. Broad network access Capabilities are available over the network and access through standard mechanisms that promote use by heterogeneous thin or thick client platform (e.g.) mobile phones, tablets, laptops, and workstations) จากอ ปกรณ ไหน จากท ไหน ก ได 9

10 Essential Characteristics 3. Resource pooling The provider s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand. There is a sense of location independence in that the customer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g. country, state, or datacenter). Examples of resources include storage, processing, memory, and network bandwidth. Essential Characteristics ลดค าใช จ าย 10

11 Essential Characteristics 4. Rapid elasticity Capabilities can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. ม ความย ดหย นส ง และรวดเร ว Essential Characteristics 5. Measured service Cloud systems automatically control and optimize resource use by leveraging a metering capabilities at some level of abstraction appropriate to the type of service (e.g. storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service. 11

12 Service Models 3 Service Models 1. Infrastructure as a Service (IaaS) 2. Platform as a Service (PaaS) 3. Software as a Service (SaaS) Service Models 1. Infrastructure as a Service (IaaS) The provider suppliers hardware and network connectivity. The tenant is responsible for the virtual machine and everything that run within it. 12

13 Service Models 2. Platform as a Service (PaaS) The tenant suppliers the application they wish to deploy, and the provider supplies all the components required to run the application. Service Models 3. Software as a Service (SaaS) The provider suppliers the application and all the components required to run it. SaaS is designed to be a turnkey solution for the tenant 13

16 Deployment Models 1. Private cloud The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g. business units). It may be owned, managed, and operated by the organization, 3 rd party, or some combination of them, and it may exist on or off premises. Deploy Models 2. Community Cloud The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises. 16

17 Deploy Models 3. Public cloud The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider. Deploy Models 4. Hybrid cloud The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g. cloud bursting for load balancing between clouds) 17

21 Hype Cycle for Cloud Computing Hype Cycle for Security Tools 21

22 SECURITY CONCERNS ON CLOUD Top 7 Threats to Cloud Computing (CSA) 1. Abuse and Nefarious Use of Cloud Computing (IaaS, Paas) 2. Insecure interfaces and APIs (IaaS, PaaS, SaaS) 3. Malicious Insiders (IaaS, PaaS, SaaS) 4. Shared Technology Issues (IaaS) 5. Data Loss or Leakage (IaaS, PaaS, SaaS) 6. Account or Service Hijacking (IaaS, PaaS, SaaS) 7. Unknown Risk Profile (IaaS, PaaS, SaaS) 22

23 Security Concerns on Cloud Firewall No longer reply on the premise firewall. Antimalware Deploy the Antimalware used for Hypervisor Layer instead of on VMOS. IPS/IDS Implement IPS/IDS as an added security layer within infrastructure in detecting potential intrusion, misuse, or insider threat, especially in Hypervisor layer. Security Concerns on Cloud Identity Management Ensure all ID s meet password management and complexity policy Passwords are stored in an encrypted format along with encrypted transmission of password between systems and applications Management has a key role to help meeting the compliance and regulatory requirements. 23

24 Security Concerns on Cloud Access Management Minimum 2-factor authentication to all applications and systems Using VPN based connection If VPN access is unavailable use a secure network protocol such as IPSEC, SSH and SSL Security Concerns on Cloud Logging including System logs Network IPS logs Identity Access log 24

25 Security Concerns on Cloud Your logging solution captures Failed login attempts Privileged access attempts Privileged activities Access attempts to sensitive data Access attempts to audit trail data Start and stop of services or applications System shutdown or start up Security Concerns on Cloud Logging Each event should contain at minimum User ID Date and Timestamp Event description Event source Event success or failure 25

26 Security Concerns on Cloud Data Security Data loss is a primary concern of IT managers across the globe. Your data protection solution address both internal and external threats Most standards required the organizations protect their data at rest data encryption Data at Rest includes files stored on servers and removable media Data in Process includes real time transactional data such as data processed in a database Data in Transit focuses on network protocols and data passing over wired and wifi networks If possible, store keys outside of your cloud environment Security Concerns on Cloud Application Security Create a website risk management plan that will heighten awareness and will protect valuable corporate and customer data from attackers 26

27 Standards and Policies Access Controls Incident Response and Management System and Network Configuration Backups Security Testing Data and Communications Encryption Password Standards Continuous Monitoring Recommendations Get security right in private cloud first, then extend to hybrid and public cloud Map workloads to the right style of cloud security Being planning for augmenting existing security delivery mechanisms with security as a Service options Separation and auditability are key issues in maintaining security Don t trust the infrastructure to secure the infrastructure 27
