4 Concepts
55a2b1d7665a995538ef4d737dc827e7
103 994-2
4.1 Introduction
The following concepts provide a reference to the architecture that is acceptable for a PAW system. So, "Let's dive in!". It is essential that a PAW follows the concept of 'browse down' [i.4], where a high-trust system administers a system of equal or lower trust. This means the PAW controls shall only be managed from ...
55a2b1d7665a995538ef4d737dc827e7
103 994-2
4.1.1 Browse Down Architecture
Browse down is where the physical device has a high level of trust and administrative access into a management system and can be managed appropriately within the high trust area. To access lower-trust systems, the device would be required to cross trust boundaries which can be protected to prevent exploitation of the d...
55a2b1d7665a995538ef4d737dc827e7
103 994-2
4.1.2 Browse Up Antipattern
The antipattern browse up is where a low-trust device is used for privileged access into a high trust environment. This could be via any means, such as VPN, Jump Box, etc. Crucially browse up means a connection is initiated from low-trust into a high-trust environment. Standard corporate devices are not suitable for pe...
55a2b1d7665a995538ef4d737dc827e7
103 994-2
4.2 Secure Communications
To ensure the integrity, confidentiality, and authenticity of communications, all connectivity involving a PAW device shall employ strong security controls. This should include the use of authenticated, encrypted, and non-repudiable protocols for all communications that leave the PAW device. Understanding the type of c...

5 Connectivity
55a2b1d7665a995538ef4d737dc827e7
103 994-2
5.1 Minimize connectivity to external networks
In most use cases, a PAW requires connectivity to external networks or internet services. But its access to external services shall be restricted to the services that are essential for it to operate. This may include receiving updates or configurations from an MDM or carrying out administrative tasks on a cloud portal....
55a2b1d7665a995538ef4d737dc827e7
103 994-2
5.2 Connectivity technology
To reduce the attack surface, make sure the connectivity methods the PAW uses, such as Wi-Fi® or cellular, are adequately secured. Public Wi-Fi networks can present a major risk to a PAW device, as they often require use of a captive portal, where the local device connects directly to the local service to authenticate....

5.3 Securely connect to administration targets
55a2b1d7665a995538ef4d737dc827e7
103 994-2
5.3.1 Introduction
A PAW needs to communicate with the systems and devices it manages and for many use cases, this could mean multiple systems or devices. Some may be less trusted or more vulnerable than others, which presents a threat to the PAW and any other system it is used to access. ETSI ETSI TS 103 994-2 V1.1.1 (2025-07) 12 Depend...
55a2b1d7665a995538ef4d737dc827e7
103 994-2
5.3.2 Remote connectivity
Many use cases for PAWs involve connecting to a system over a network, either locally or remotely. It is important that communications from the PAW are protected from any threats on that network: • Secure protocols, such as TLS or IPSec, should be used to authenticate the systems or networks which are being connected. ...
55a2b1d7665a995538ef4d737dc827e7
103 994-2
5.3.3 Direct connectivity
Some use cases may require direct physical connectivity to the administrated device, such as over serial or Ethernet links. When using direct physical connectivity to a system or asset, the controls on the PAW device are the only layer of security between the PAW device and the asset being managed. It is important to u...
55a2b1d7665a995538ef4d737dc827e7
103 994-2
5.3.4 Isolated devices and systems
In many cases, a PAW which is used to manage standalone or isolated equipment is also used to manage or connect to other systems and networks. Where this is the case, the PAW device acts as a bridge between the systems and networks, even if the connections are not active at the same time. Even if a network is temporari...
55a2b1d7665a995538ef4d737dc827e7
103 994-2
5.3.5 Less trusted systems
A system or device managed by a PAW could be considered less trusted for several reasons, for example: • it processes high-risk data; • it is one of many systems which need segregating from one another; • a third party has privileged access to it. ETSI ETSI TS 103 994-2 V1.1.1 (2025-07) 13 If one of these systems is co...

6 Third Parties and PAWs
55a2b1d7665a995538ef4d737dc827e7
103 994-2
6.1 Definitions
A third party is characterized as an individual or entity external to an organisation. This typically implies there is no direct control over the employees working on behalf of the contracting organisation. It is crucial to establish contractual agreements with any third-party company to ensure compliance with legal an...
55a2b1d7665a995538ef4d737dc827e7
103 994-2
6.2 Apply equivalent controls to third parties
If a third party is compromised, it offers an access route to all the organisations to which they provide services. This is why third-party access is viewed as a significant risk and should be managed appropriately. To ensure that the PAW solution is an effective defence, any third party that requires access to the con...
55a2b1d7665a995538ef4d737dc827e7
103 994-2
6.3 Third party acting as a Managed Service Provider
Engaging a third party to design, construct, and/or upkeep the privileged system poses a substantial threat to a business's operational security. The business's security is intrinsically linked to the third party's security, given their need for significant privileged access. If a PAW system is to be developed and cons...

8 Threats and Mitigations
There is significant risk over the communication channels between a PAW device, and its corresponding network(s), given the privileged access the device is protecting. If the device itself is well-protected, then an attacker may refocus attention towards the communications between the device and any external networks. ...

3.1.1 Definitions
Location registration means that the PLMNs keep track of where MSs are located in the system area. The location information is stored in functional units called location registers. Functionally there are four types of location registers: - the home location register (HLR) where the current location and all subscriber p...

3.1.2 Procedures
Procedures related to location registration are specified in Technical Specification GSM 03.12. They comprise: i) location updating which enables the MS to inform the network that its location area has to be updated, i.e. the MS has received a location area identity which is different from that contained in its memory....

3.3 Call re-establishment
Re-establishment of a call may be performed when a traffic channel (TCH) has been lost during the call, e.g. when a handover could not be completed in time. Call re-establishment is only performed on TCHs and when the call is in the connected state (see Technical Specification GSM 04.08). The procedures are specified i...
