A system can continue operating normally even while it contains overprivileged accounts, unpatched servers, publicly exposed data, or improperly configured security devices.
The real issue is not simply determining whether vulnerabilities exist. Businesses also need clear answers to more practical questions:
Which systems are currently exposed to risk?
Which weaknesses could be exploited?
What data and business operations could be affected?
Which issues should be remediated first?
Are the existing security controls actually effective?
Information security assessment services help businesses answer these questions by reviewing infrastructure, systems, applications, user accounts, security configurations, and operational processes.
At the end of the assessment, the business should receive more than a list of technical alerts. It should gain a clear view of its current risk exposure, supporting evidence, and a prioritized remediation plan.
What will be assessed?
The assessment scope is defined based on the company’s actual environment and objectives. Instead of applying the same checklist to every organization, the assessment provider should identify critical assets, possible attack paths, and systems that process or store sensitive data.
A typical information security assessment may cover the following areas.
Network infrastructure and security devices
Security specialists review the network architecture, connections between system zones, firewalls, routers, switches, VPNs, and services exposed to the internet.
The assessment may include:
Internal network segmentation
Connectivity between user networks and servers
Services and ports exposed to the internet
Firewall access rules
VPN and remote-access configurations
Devices running outdated firmware
Unnecessary management services
The ability to isolate systems during an incident
The results help the organization determine whether an attacker could move from a standard endpoint to a critical server or whether an internal service has been unintentionally exposed to the internet.
Servers and operating systems
Servers host applications, store data, and support critical business operations. A single weak administrator account or an unpatched service may provide an entry point for attackers.
Common assessment areas include:
Operating system versions
Patch status
Active services and open ports
Administrator accounts
Password policies
Folder and data access permissions
Logging configurations
Anti-malware controls
Backup and recovery mechanisms
Unused software
The business will be able to identify which servers require immediate attention, whether the issue relates to patching, configuration, or access control, and what could happen if the weakness is exploited.
Websites, applications and APIs
Websites and applications are frequently targeted because they are directly accessible from the internet.
The assessment may review:
Authentication mechanisms
User authorization
Session management
Input validation
Unauthorized data access risks
Web server misconfigurations
Outdated components and libraries
Exposed or insufficiently protected APIs
Publicly accessible sensitive files
Technical information disclosure
For systems that require deeper validation of real-world exploitability, businesses can combine the assessment with IPSIP’s penetration testing services.
For a faster review of common website weaknesses, businesses may also consider website vulnerability scanning services.
Accounts and access orivileges
Many security incidents do not begin with highly sophisticated attack techniques. They start with shared accounts, weak passwords, former employee accounts that remain active, or excessive administrative privileges.
The assessment may include:
Active account inventories
Dormant or unused accounts
Shared accounts
Privileged accounts
Password policies
Multi-factor authentication deployment
Access provisioning and deprovisioning processes
Privileged access controls
Unusual login activity
The results help businesses reduce the risk of compromised accounts being used to access data, modify configurations, or expand an attack.
For critical administrator accounts, businesses may need to implement a Privileged Access Management solution.
Cloud environments
Moving systems to the cloud does not automatically make them secure.
Common cloud risks may include:
Publicly accessible storage repositories
Excessive IAM permissions
Access keys that are not rotated
Administrator accounts without MFA
Security groups open to all IP addresses
Disabled or incomplete logging
Inadequate data encryption
Abandoned testing resources
Poorly controlled connectivity between cloud and on-premises environments
A cloud security assessment helps businesses identify misconfigurations that could lead to data leakage, account compromise, or unauthorized access to cloud resources.
Endpoints
Employee computers, remote-work laptops, and mobile devices are often the starting point of phishing, account theft, or malware campaigns.
The assessment may cover:
Operating system versions
Patch status
Endpoint security software
Local administrator privileges
Disk encryption
External devices
Unauthorized software
Screen-lock policies
Remote device management
Compliance with internal security policies
The results help organizations identify devices that fall outside centralized management or may expose company data when employees work remotely.
Monitoring and incident response capabilities
A business may invest in multiple security tools and still fail to detect suspicious activity if logs are not collected or alerts are not actively handled.
The assessment may examine:
Whether security logs are being generated
How long logs are retained
Whether abnormal logins are monitored
Whether administrator configuration changes trigger alerts
Whether malware or suspicious traffic can be detected
Who is responsible for receiving alerts
Whether an incident response process exists
Whether systems can be restored after an incident
Whether backup data is available and usable
Businesses without a dedicated monitoring team may consider IPSIP’s 24/7 SOC services.
How is an information security assessment conducted?
An effective assessment must follow an agreed scope, minimize disruption to production systems, and generate results that can be converted into practical actions.
Step 1: Understand the business requirements and current environment
IPSIP works with the business to identify:
Systems to be assessed
Assessment objectives
Critical assets
Sensitive data
Authorized testing scope
Implementation timeline
Systems that must not be affected
Technical points of contact
At this stage, the business does not need to know exactly which tools or methodologies should be used. The most important step is to provide information about the current environment and the problem that needs to be addressed.
Step 2: Define the assessment scope
The scope may be defined based on:
Number of IP addresses
Number of servers
Number of websites
Number of applications and APIs
Cloud environments
Internal network systems
Branches or physical locations
User accounts and groups
Systems storing critical data
A clearly defined scope helps the organization control costs, manage timelines, and avoid overlooking important assets.
Step 3: Collect information and review the current state
Security specialists collect technical information, review the attack surface, and examine existing configurations.
This may include:
Identifying internet-facing assets
Reviewing domains and related services
Checking open ports
Identifying system versions
Reviewing security configurations
Analyzing access privileges
Checking patch status
Comparing actual assets with the organization’s inventory
This stage often reveals assets that are no longer properly managed, such as old servers, forgotten subdomains, testing accounts, or abandoned services.
Step 4: Identify vulnerabilities and security weaknesses
Specialized tools may be used for broad coverage, followed by expert analysis and manual validation.
The process does not simply record vulnerability names. It also evaluates:
Whether the vulnerability truly exists
Where it can be accessed from
What conditions are required for exploitation
Which assets are affected
What data may be exposed
Which existing controls reduce the risk
How urgently the issue should be remediated
Validation reduces false positives and prevents IT teams from wasting time on large volumes of irrelevant findings.
Step 5: Analyze the business impact
A technical weakness becomes meaningful only when evaluated in the context of business operations.
For example, the same unpatched server may represent different levels of risk depending on whether:
It is exposed to the internet
It stores customer data
It is only used in a testing environment
It can access accounting systems
It supports a critical business service
Additional compensating controls are in place
Therefore, findings should be prioritized based on both technical severity and business impact, rather than relying solely on a scanner-generated score.
Step 6: Deliver reports and a remediation plan
After the assessment, the business receives both an executive report and a detailed technical report.
IPSIP clearly presents:
The identified issue
The affected asset
The level of risk
Supporting evidence
The root cause
The potential impact
Recommended remediation
Remediation priority
The team or department responsible
Long-term improvement areas
Step 7: Retest after remediation
After the IT team completes the remediation work, the organization may conduct a retest to confirm that:
The vulnerability has been properly resolved
The new configuration has not introduced additional risks
The remediation measure is effective
Critical issues can no longer be exploited
This step is important because closing a technical task does not always mean that the underlying risk has been eliminated.
What will the business receive after the assessment?
The most important deliverable is not a report containing hundreds of pages. The organization needs clear information that supports decisions and remediation.
A clear view of the current security posture
The business will understand the overall condition of its systems, which areas carry the greatest risk, and whether existing security controls are functioning properly.
Instead of handling isolated incidents, management can see the relationship between infrastructure, accounts, data, applications, and operational processes.
A prioritized risk list
Not every finding needs to be fixed at the same time.
The report helps classify findings into:
Risks requiring immediate action
Risks that should be addressed in the short term
Issues that should be included in an improvement plan
Long-term optimization recommendations
Risks that may be temporarily accepted with compensating controls
This prioritization helps the organization use its budget and technical resources more effectively.
Evidence for each finding
Every weakness should include enough evidence for the IT team to verify and remediate it.
Evidence may include:
IP addresses
Hostnames
URLs
Network ports
Software versions
Screenshots
Relevant configurations
Affected accounts or permission groups
Safe reproduction steps
This prevents situations where a report provides only a vague conclusion without showing where the actual problem exists.
Practical remediation guidance
Recommendations should not stop at general statements such as “update the system” or “improve security.”
The business needs to understand:
Which component should be updated
Which configuration should be changed
Which permission should be revoked
Which port should be closed
Which accounts require MFA
Which data should be encrypted
Which logs should be collected
Which policy should be added
Which temporary mitigation can be applied if immediate remediation is not possible
A basis for security budget planning
After the assessment, the business can distinguish between actual priorities and investments that are not yet necessary.
For example, the organization may determine that it should prioritize:
Fixing misconfigurations
Upgrading firewalls
Improving device management
Deploying MFA
Building SOC capabilities
Conducting deeper penetration testing
Training employees
Improving backup systems
Developing an incident response process
This reduces the risk of purchasing additional tools while fundamental security weaknesses remain unresolved.
Support for audits and compliance
The assessment report may help the organization demonstrate that it has proactively reviewed risks, identified weaknesses, and developed a remediation plan.
Depending on the organization, the report may support:
Customer security reviews
Supplier assessments
Internal audits
Certification preparation
Parent-company requirements
Personal data protection reviews
Information system assessments
Annual security planning
Information security assessments in Vietnam’s 2026 legal context
The year 2026 marks an important legal transition for cybersecurity and data protection in Vietnam.
The Cybersecurity Law No. 116/2025/QH15 was enacted on December 10, 2025, and took effect on July 1, 2026.
As of July 2026, businesses are no longer dealing solely with technology risks. They must also consider their responsibilities for system protection, cybersecurity governance, and data security under the new legal framework.
The Personal Data Protection Law No. 91/2025/QH15 took effect on January 1, 2026. The Government also issued Decree No. 356/2025/ND-CP, which provides detailed regulations and implementation measures for the Personal Data Protection Law.
These developments make information security assessments especially relevant for organizations that:
Collect customer information
Store employee records
Process personally identifiable information
Use cloud services
Share data with third-party providers
Operate websites and applications
Allow employees to work remotely
Process data for overseas parent companies or partners
A technical security assessment does not replace legal advisory services or the preparation of compliance documentation.
However, it helps the business verify a critical issue: whether the security controls described in internal policies have actually been implemented and are operating effectively within the real environment.
For example, a business may state that access to personal data is restricted, while the assessment reveals that an internal folder is accessible to all employees.
The organization may state that administrator accounts are controlled, while the system still contains shared privileged accounts with no identifiable owner.
The gap between policy and actual configuration is one of the key risks that an information security assessment should uncover.
For information systems classified by security level, security obligations may also relate to Decree No. 85/2016/ND-CP and Circular No. 12/2022/TT-BTTTT on information system security by level.
For this reason, businesses should treat information security assessments as a recurring governance activity, rather than a one-time procedure performed only when an inspection is expected.
How is the cost of an information security assessment calculated?
The cost depends directly on the scope and depth of the assessment.
Common pricing factors include:
Number of IP addresses
Number of servers
Number of websites
Number of applications and APIs
Complexity of the environment
Internal or external assessment scope
On-premises or cloud infrastructure
Manual testing requirements
Exploit validation requirements
On-site or remote delivery
Retesting after remediation
Required report detail
Implementation timeline
To receive an accurate quotation, businesses should prepare at least:
A list of systems to be assessed
An architecture diagram, if available
The number of servers and devices
A list of domains, websites, or applications
The primary project objective
The expected timeline
Any special security or operational requirements
When the scope has not yet been clearly defined, IPSIP can conduct an initial review and recommend an appropriate assessment plan before implementation.
Questions to answer before starting the assessment
Before the project begins, the organization should align internally on several questions:
Which systems are the most critical?
Which data should be protected first?
Are there any systems that must not experience downtime?
Which team will coordinate the assessment?
Who will receive and act on the report?
Does the organization have resources available for remediation?
Is retesting required after remediation?
Will the results be used for internal governance or compliance purposes?
Answering these questions helps ensure that the project focuses on the right risks and produces results that can be used immediately.
