What does it comprise?
While PAM solutions vary in their design, most of them consist of these
three components:
• Access Manager – Manage all employee access from a single portal
• Session Manager – Monitor all privileged user actions in real-time
• Password Manager – Protect passwords and enforce password policies

Privileged Access
Management
Gartner has named privileged access management the #1 cyber security priority for organisations. But what
exactly does privileged access management entail?
‘Privileged access’ encompasses access to critical systems - computers, networks and network devices, software
applications and other digital assets. Privileged access management (PAM) is thus, the combination of tools and
technology used to secure, control and monitor access to an organisation’s critical information and resources.

An overview
Key components of PAM

The Session Manager provides real-time monitoring of
privileged users to prevent and detect suspicious activity. It
tracks and creates an audit trail of actions taken during a
privileged account session.
The Password Manager helps with controlling passwords
and enforcing password policies. This allows regular
rotation and revocation of passwords while maintaining
them in a centralised and encrypted vault.
The Access Manager helps security teams to manage all
employee access on a single portal, from which:
- Privileged user can request access, and
- Administrators can disable a privileged user’s access

Overview
Why do organisations need PAM?

A standard data breach can cost and organisation an average of USD3.92 million. Enterprises that prioritise
privileged credential security are able to ensure that their operations will not be interrupted by a breach, hence
by creating a formidable competitive advantage over their peers in time and costs.

Benefits of PAM
Why do organisations need PAM?
Powerful security solution
• PAM is a powerful security solution that can be used to improve insights into vulnerability
assessments, IT network inventory scanning and identity governance, among other things. This
enhancement of cyber security serves as a deterrence to many cyber criminals.
Saves time and money
• Most cyber security solutions only reduce risk but bring no additional business value. However,
employing the right PAM solution can increase productivity by giving employees access to systems
and applications faster and more securely. This enables CISOs to get more done with the same
budget.
Fast track to compliance
• With strong security control recommendations, PAM develops a good baseline of policies that can
help to fast-track your compliance standards to align with industry and government regulations.
Quick recovery from cyber-attacks
• A PAM solution enables you to quickly audit privileged accounts that have been used recently,
identify passwords that have been changed, and determine which applications have been executed.

Case study: Capital One Bank
How breaches could have been prevented with PAM
Read more: The New York Times
One of the most high profile cases of 2019 was the data breach of Capital One Bank, of which over 100 million customer
accounts and credit card applications were exposed.
How the breach occurred:
Paige Thompson, former Amazon AWS employee (Capital One’s cloud hosting
service), took advantage of misconfigurations in Capital One’s cloud services
and firewalls. She bypassed the firewalls, used web application firewall
credentials to obtain privilege escalation and gained access to more and more
sensitive data.
Consequences:
As a result of the breach, the following were stolen from Capital One’s
database:
- More than 140,000 social security numbers
- 1 million Canadian Social Insurance numbers
- 80,000 pieces of banking and credit information
- Undisclosed number of names, addresses, credit scores, and more

Case study: Facebook

In October 2019, global social media giant, Facebook, encountered yet another data breach when hackers took over a
single account belonging to one of its biggest data partners.
Hackers commandeered the personal account of a LiveRamp employee who
had privileged access to advertising accounts on Facebook. Using that personal
account, hackers gained access to the company’s Business Manager account,
allowing them to run ads with LiveRamp’s customers’ money.
Consequences:
Using that access, hackers ran a series of ads on LiveRamp’s customer accounts
on Facebook. They spent thousands of those victims’ dollars to trick viewers
into buying fake products.
One of the ads had been viewed more than 60,000 times and directed visitors
to a page designed to steal people’s credit card numbers.

Case study: Marriott International
Read more: CSO Online
In late 2018, hotel chain Marriott International discovered unauthorised access within Starwood’s reservation system, a
subsidiary Marriott acquired in 2016.
Internal investigation determined that Starwood’s network was compromised in 2014, which meant that there had been
unauthorised access for 4 years into Starwoods’ systems by the time it was found out.
Attackers managed to take control of a user account with privileged
access to make a database query.
The user credentials were stolen using a Remote Access Trojan (RAT)
along with Mimikatz, a tool used to find out username/password
combos in system memory, that were placed onto the server.
Consequences:
Up to 500 million guest records were stolen, including extremely
sensitive information like credit card and passport numbers.

How PAM might have helped
1. Real-time session monitoring could have caught and detected the suspicious activities of hackers,
terminated such sessions, and alerted the security teams, preventing an incident from happening.
2. The segmentation of user privileges could have prevented hackers from bouncing from one
resource to another.
3. Besides multi-factor authentication (MFA), PAM also checks for circumstances surrounding
privileged access (e.g. time and IP location). If caught as unauthorised, access would be denied
even if credentials were otherwise valid.
4. A strong PAM solution would have hidden the very existence of sensitive resources to users who
do not have privileged access. If hackers were in the system with credentials that have no
database access, they would not even be able to see personal information, much less query
against it and retrieve it.
