10. Information security (InfoSec)
• Set of practices that protect information and
information systems from unauthorized access, use,
information disclosure, disruption, modification, or
destruction
• Goal of information Security is to provide:
– Confidentiality , Integrity and Availability
• Authentication Authorization and Accounting (AAA)
• Security Mechanisms ensure right users have access
to right resources at the right time
• Auditing enables assessing effectiveness of the
security mechanisms

11. Information Assurance (IA)
• The process of getting the right information
to the right people at the right time
• Ensure the integrity, availability, authenticity,
non-repudiation and confidentiality of user
data
– Operating on the Cloud do so legal (Allowed Services)
– Accessing only those data for which they have rights
– Access only to the degree their policies and their roles
permit
• IA Model

12. IA vs InfoSec
• Information Security: The protection of information and information systems from unauthorized access, use, disclosure, disruption,
modification, or destruction in order to provide confidentiality, integrity, and availability.
• Information Assurance: Measures that protect and defend information and information systems by ensuring their availability, integrity,
authentication, confidentiality, and non-repudiation. These measures include providing for restoration of information systems by incorporating
protection, detection, and reaction capabilities.

17. Cloud Security Threats
• A data breach is the most common fear related to cloud security
• A breach may occur due to a simple human error, targeted attack, application glitches, or
poor security practices
• may involve release of personal information of company clients, patient health information,
financial information, trade secrets, personal identification information, etc
Data Breach
• using their login information and remotely access sensitive data present on the cloud
• access the sensitive information, but also falsify or manipulate the data using their hijacked
credentials
Account Hacks
• APIs that allows the customers to manage and interact with the cloud services
• communication between applications turns into an exploitable security risk for businesses.
Hijacked Interfaces and APIs

18. Cloud Security Threats Cont.
• Exploitable bugs within the programs can be used by hackers to infiltrate
a cloud to steal data, take control of the system as well as cause
disruption within the service operation
System Bugs
• Employees with access to the cloud-based services can misuse their
power and access the customer accounts, financial information
Insider Threats
• Attackers can inject malicious codes into cloud services such that they
are viewed as a part of the authentic code and runs within the cloud
serves
Malware Codes

19. Cloud Security Threats Cont.
• Data can be lost on the cloud due to various reasons
• This includes natural disasters such as earthquakes, floods, or fire
Data Loss
• Many companies tend to rush into cloud services without taking any pains to verify
the company’s claims.
• This can be a serious security risk as you do not know if the cloud service provider will
match your needs of security and privacy.
Detailed Cloud Provider Verification
• Denial of Service (DoS) occurs when targeted cloud service is forced to use system
resources such as memory, disk space, processor power, network bandwidth, etc.
• The attackers slow down the system to such an extent that all legitimate users are left
without access to services.
Denial of Service

20. Security Best Practices on Cloud
• Planning
• Development and Deployment
• Operation
• Decommissioning
• Develop a multiple-CSP strategy
Perform Due Diligence
• Identify and Authenticate Users
• Assign User Access Rights
• Create and Enforce Resource Access Policies
Managing Access ( Remember : Principle of least privilege )
• Protect Data from Unauthorized Access
• Ensure Availability of Critical Data
• Prevent Disclosure of Deleted Data.

23. Tips
Defense-in-depth (Layard Approach)
• Strategy in which multiple layers of defense
are deployed throughout the infrastructure
to help mitigate the risk of security threats in
case one layer of the defense is
compromised.
• Provide additional time to detect and
response to an attack
• Reduces the scope of a security breach
• Recuded velecority of the attack

34. AWS Identity and Access Management
• All AWS accounts have root user credentials (that is, the
credentials of the account owner).
• These credentials allow full access to all resources in the
account.
• You may need AWS account root user access for specific tasks,
such as changing an AWS support plan or closing your account
• AWS recommends that you delete your root user access keys and then
create AWS Identity and Access Management (IAM) user credentials
for everyday interaction with AWS

36. AWS Identity and Access Management
• AWS Identity and Access Management (IAM) enables you to
manage access to AWS services and resources securely.
– Using IAM, you can create and manage AWS users and
groups, and use permissions to allow and deny their
access to AWS resources.
• IAM is a feature of your AWS account offered at no
additional charge.
• You will be charged only for use of other AWS services by
your users

39. How it works?
• IAM assists in creating roles and permissions
• You can create users in IAM, assign them individual security credentials (in other words, access keys,
passwords, and multi-factor authentication devices), or request temporary security credentials to
provide users access to AWS services and resources. You can manage permissions in order to control
which operations a user can perform.
Manage IAM users and their access
• You can create roles in IAM and manage permissions to control which operations can be performed
by the entity, or AWS service, that assumes the role. You can also define which entity is allowed to
assume the role. In addition, you can use service-linked roles to delegate permissions to AWS
services that create and manage AWS resources on your behalf.
Manage IAM roles and their permissions
• You can enable identity federation to allow existing identities (users, groups, and roles) in your
enterprise to access the AWS Management Console, call AWS APIs, and access resources, without the
need to create an IAM user for each identity. Use any identity management solution that supports
SAML 2.0, or use one of our federation samples (AWS Console SSO or API federation).
Manage federated users and their permissions

40. Best Practices
• Create individual usersUsers
• Manage permissions with groupsGroups
• Grant least privilegePermissions
• Turn on AWS CloudTrailAuditing
• Configure a strong password policyPassword
• Enable MFA for privileged usersMFA
• Use IAM roles for Amazon EC2 instancesRoles

44. AWS Infrastructure Overview
• VPC [Virtual Private Cloud ] lets you provision a logically isolated section of
the Amazon Web Services (AWS) Cloud where you can launch AWS resources
in a virtual network that you define. You have complete control over your
virtual networking environment, including selection of your own IP address
range, creation of subnets, and configuration of route tables and network
gateways
• EC2 [Elastic Compute Cloud] is a web service that provides resizable compute
capacity in the cloud. Amazon EC2 reduces the time required to obtain and
boot new server instances to minutes, allowing you to quickly scale capacity,
both up and down, as your computing requirements change
• S3 (Simple storage Service) provides developers and IT teams with secure,
durable, highly-scalable object storage. Amazon S3 is easy to use, with a
simple web services interface to store and retrieve any amount of data from
anywhere on the web.

45. VPCs and Subnets
• A virtual private cloud (VPC) is a virtual network dedicated to your AWS account. It is
logically isolated from other virtual networks in the AWS Cloud. You can launch your
AWS resources, such as Amazon EC2 instances, into your VPC. You can specify an IP
address range for the VPC, add subnets, associate security groups, and configure
route tables.
• A subnet is a range of IP addresses in your VPC. You can launch AWS resources into a
specified subnet. Use a public subnet for resources that must be connected to the
internet, and a private subnet for resources that won't be connected to the internet.
For more information about public and private subnets, see VPC and Subnet Basics.
• To protect the AWS resources in each subnet, you can use multiple layers of security,
including security groups and network access control lists (ACL).

46. Security Group
• A security group acts as a virtual firewall that controls the traffic for
one or more instances.
• When you launch an instance, you can specify one or more security
groups; otherwise, we use the default security group.
• You can add rules to each security group that allow traffic to or from
its associated instances.
• You can modify the rules for a security group at any time; the new
rules are automatically applied to all instances that are associated
with the security group.
• When we decide whether to allow traffic to reach an instance, we
evaluate all the rules from all the security groups that are associated
with the instance.

47. Network Access List
• A network access control list (ACL) is an optional layer of security for your
VPC that acts as a firewall for controlling traffic in and out of one or more
subnets.
• You might set up network ACLs with rules similar to your security groups
in order to add an additional layer of security to your VPC.
• Your VPC automatically comes with a modifiable default network ACL.
• By default, it allows all inbound and outbound IPv4 traffic and, if
applicable, IPv6 traffic.
• You can create a custom network ACL and associate it with a subnet.
• By default, each custom network ACL denies all inbound and
outbound traffic until you add rules.
• Each subnet in your VPC must be associated with a network ACL. If you
don't explicitly associate a subnet with a network ACL, the subnet is
automatically associated with the default network ACL.

48. Network Access List Cont.
• You can associate a network ACL with multiple subnets; however, a subnet can be
associated with only one network ACL at a time. When you associate a network ACL
with a subnet, the previous association is removed.
• A network ACL contains a numbered list of rules that we evaluate in order, starting
with the lowest numbered rule, to determine whether traffic is allowed in or out of
any subnet associated with the network ACL. The highest number that you can use
for a rule is 32766. We recommend that you start by creating rules in increments (for
example, increments of 10 or 100) so that you can insert new rules where you need
to later on.
• A network ACL has separate inbound and outbound rules, and each rule can either
allow or deny traffic.
• Network ACLs are stateless; responses to allowed inbound traffic are subject to the
rules for outbound traffic (and vice versa).

49. Network Access List vs Security Group
Network Access List Security Group
Network ACL is Stateless changes applied
to incoming will not be applied to Security
Group.
Security Group is stateful, any changes
applied to an incoming rules is
automatically applied to an outgoing rule
Network ACL are tied to the subnet Security groups are tied to an instance
Network ACL is the second layer of the
defense
Security group is the first layer of the
defense.
Network ACL rules are applied in order,
with rules with lower number processed
first.
Security group all rules are applied.
